HELLO! =)

2006-10-02T19:23:00.000-05:00

Hello people...hows everyone doing? i am very bored right now and i miss this site so i just thought why not just make a post...and yeah...=)...so iunnno...but how is everyone..

"MUSTA NA!" GUYS

2006-06-17T21:52:00.000-05:00

PLEASE SOMEONE REPLY OR COMMENT ON THIS!!!
hopully someone reads this..i really need help with this thing..
actually it's not a very big problem but it's for our video project...
Ms. Armstrong..or anyone...classmates? friends?...buddies? Ms. Nicholson? hahahaha
does anyone know how to verify an average..? say i added 2,3,4,2,3 together..
the sum is 14..now i divided it by 5 and i got 2.8..how do i check if 2.8 is the right answer..
is there any way?
please please please..reply to this!!!
thanks so much.

Well Jellybeans... all of your hard work was rewarded today. I hope you enjoyed the imax movie as much as I did. Here are the pictures. Are you better looking with glasses or without?

Pssst...I have a secret - pass it on!!

2006-05-04T21:03:00.000-05:00

Well, well my jellybeans, it seems that you have fallen off the blogging wagon. Where is everyone? No scribe posts, no good commenting, no great sites for us to check out. What's going on?

Today I was thinking! (No I didn't hurt myself), but I did realize that you are almost grade 10's. My little jellybeans are growing up so quickly. That makes it the perfect time to challenge you to out do the fabulous work that you were doing earlier in the year. Would you like a little incentive??? Here it is... Mr. Kuropatwa has started a wiki (it's a type of website that you can go to and edit as you wish) that is called The Scribe Post Hall of Fame.

Now for the challenge. I want each of you to try and out do, out scribe, and out teach each other. I know that you are all incredibly capable of exceeding my expectations. As for the secret, one of you has already been nominated by a Grade 8 teacher at Sargent Park. Check out the link to find out which post was deemed hall of fame worthy. Then pass on the info to the others. I want to see if everyone knows by lunch time tomorrow. Bet you can't do it, or can you.

Ms. Armstrong

So long... for now??

2006-05-02T17:04:00.000-05:00

Hello grade nines!

It's been such a long time since I checked out this blog and I have to say that reading through the last bunch of posts made me feel so proud of the work that you're doing. Keep it up! Today is my last day of student teaching at Daniel McIntyre. Once again, you were all a part of making my learning experience here a memorable one. Now you just have to work at convincing Ms.Armstrong that it's time for another baby (right girls?! Remember the babysitting?). That way I can come back and cover her maternity leave... :)

By the way, Azrael and Uyen- fantastic work in the musical! You can tell you were having a blast! Get involved in as much as you can in high school when there are so many opportunities to do so. You never know what kind of memories you'll create or how you'll impact someone else just by being a positive participant.

There's really only one month left of grade nine... give it all you got!

I'll miss you!

Time to kill PART 2

2006-04-20T18:08:00.001-05:00

oh this is the part i hate.
DO I HAVE TO

arvin's conscience : "DUHH!!!"

FINE!

hmph.

on to the harder part.
i already dealt with equations like..
"12 = 1 + x"
and..
"12 = x - 1"

now, how do we find the value of "X" if we have an equation like,

3x = -6

now. the goal is still the same.

Find the Value of the variable.

we have 3 set's of x's that are equal to (-6)
this is how it would look like in algebra tiles.

now, our problem here is that we have 3 sets of x's and the value of the total of those 3 sets is on the other side.
now, we still need to isolate the x's
since we have
3x = -6
we have to cancel out the co-efficient for x
how? by dividing it.
3x is equal to 1x or simply, x.
3
remember the what u do to one side u do to the other rule?
well.. since u divided one side by 3 (to cancel out the co-efficient) we divide the other side by 3 too.
so we have

3x = -6
3
it would look like this in algebra tiles,

the result would be,

or in plain arithmetic

x = -2

get it? easy isnt it?
okay.

now let's flip it.
say we have an equation

x = -2
3

Now, what we know is that 1/3 of the variable x is equal to -2
to get the FULL value of the variable "x"
we have to multiply it by the number the variable is being divided by. in this case, that number is 3.

so we multiply BOTH sides of teh equation by 3.

and because we were dividing the variable by 3, multiplying it by 3 nullifies BOTH of the operations, leaving it simply as, X. and viola, we have isolated X.
but since we used teh process of multiplying (x/3) by 3, we have to do the same thing to the other side of the equation. therefore, we multiply (-2) by 3.
after all the calculations, the equation would look something like this...

x = -6

there.
i have explained all four of the operations. but the next.. is the multi operation equations. (WOW! it rhymed~!) but unfortunately. i dont think im in the mood to do that today. hahaha.. sorry guys. cya later.

Time to kill = Time to catch up

2006-04-20T18:08:00.000-05:00

HELLO PEOPLE!It's been a while since I think ANYONE got on this site to make a post and no, I don't blame Mrs. Armstrong, she has enough on her mind. And I think we should be responsible enough to be able to take care of this. I mean,this is for our good.
ANYWAY..BACK TO Math. In my next posts, im going to TRY and catch up to what we did. aights?kk. be ryt back, preparing my notes.

Number 1

What we are doing in math now is solving EQUATIONS.
now. the question is not "What's the answer", "it's what's the value of X?"

let's say we have an equation where the ask us to find the VALUE of the variable X.

let's say we have..

"12 = 1 + x"

now the question is what is the value of x?
now take a look at the equation. looks hard? well. visualize this.
it's on a see-saw kind of thing. the "=" sign is the middle of it.
the numbers are the things on either side.
in algebra tiles, this is what it would look like.

now. The balance is "Balanced" meaning whatever is one the left side,
is equal to whatever is on the right side.
now. To get the value of X. The objective here is. ISOLATE the VARIABLE.
how do we do that? We take off whatever is with the "X"
now we cant just take it away. We need to take it away using Zero models.
to make a Zero Model with (+1) we need to add it's opposite to it. so we add (-1) to make it a Zero-Model. But there's a rule for it. to keep the two sides balanced, we need to do the same thing we did to the other side.
so if wee added a (-1) to one side, we add (-1) to the other one too.
now.
our question is now
"12 = 1 + x"
we already know how to make zero models. so to get the "X" by itself, we need to delete the (+1)
near it. (by making zero models of course.)

so our equation now goes, +12 -1 = 1 -1 + x
notice that i added a -1 to both sides. this is to KEEP IT BALANCED.
this is what it would look like on algebra tiles.

now that we cancelled out the +1 on the side with the variable. the is nothing with the variable.
now that equation reads..
11 = x

there, we found out what "x" is equal to.

that's basically how you do it. but that's only with addition & subtraction.
if the equation was,

"12 = x - 1"

you would still make zero models to isolate the variable x.

12 +1 = x -1 +1

the zero model on the side where the X is cancels out the "-1 and leaves nothing but the variable X behind. now, on the other side of the equals sign, we did the same thing to keep the balance.
because we added on (+1) to the side with "X" we have to add (+1) to the side with the numbers in it too. JUST TO KEEP IT BALANCED.
the result would be..

13 = x

there, i have finshed my post on that part. i'll be posting the next part shortly. the one abou multiplication and division.

I have a question, do we obsolutely HAVE to use those blue sheets as tags ? Or are we allowed to do them on our own ? because I forgot to grab some and I want to finish my unit tonight. So can somebody be so kind as to answering my questions :)

Hey Guys

2006-04-06T15:06:00.000-05:00

whoah i haven't been here in such a long time...
well here i tried my best to find a good site for us to study for
tomorrow's test.
Actually if you work on the review on
page 320 #5-6 #12-37 it's a very good practice.

But here are the sites that I found.
Translation
Reflection
Rotation
Dilations

would you look at that...I'm missing distortion.
Well, I tried looking for a good site but I seriously can't but i'll give you some informations
about Distortion.
Distortion:
I'm gonna do this in my head.
It's a wonkt shape;
not equal;
the mapping rule is different. e.g- (x,y) -->( 3x,6y)
it's not a congruent or similar...

that's all i can find in my head and i'm running out of time...
my advice is look at your 3point word and your notes and work it'll be helpful!!!
well that's it guys see ya!

Spring Break! Puzzles!! :)

2006-03-22T19:07:00.000-06:00

Hello! This Have Some Over Spring Break! But Here are Some Puzzles To Pump Some Brain Power Over The Spring Break Weekend! :) Woo-Hoo!! Good Luck! :P Hehe

Puzzle #1: How many hexagons, in total,
can you find in this puzzle. Clue: there are more than 45.

Answer Puzzle #1: There are 64 hexagons in total. There are 37 single hexagons, 19 hexagons which contain 7 smaller hexagons, 7 hexagons which contain 19 smaller hexagons and one large hexagon which contains all of the smaller hexagons.

Puzzle #2: Above is 99, moving only two lines, can you turn this into 25?

Answer Puzzle #2:

Puzzle #3: Can you draw exactly 4 straight lines
that pass through ALL 9 spots, without removing your pen from the paper?

Answer Puzzle #3:

Puzzle #4: Place the digits from 1 to 9 into
the circles so that the sum of the numbers in each straight line is the same.

Answer Puzzle #4:

Finally.....

Puzzle #5: What number comes next in this sequence?

986888
724864
143224

Answer Puzzle #5: 468: each line is generated by multiplying two digits at a time of the previous line. 986888 = (9x8)(6x8)(8x8) = 724864 = (7x2)(4x8)(6x4) = 143224 = (1x4)(3x2)(2x4) = 468.

Post Your Answers In Comment Box And I'll Post The Correct Answer On the Last Day Of Spring Break!!

Thanks: Braingle

2006-03-20T18:55:00.000-06:00

Tribond time.

>Overhead Projector

answer?
Dilatations.

Dilatations are the transformations of shapes by making them BIGGER or smaller.
The text book Glossary puts it in a more simple way. The transformation that changes the size of an object.
Out of all honesty *sounds like something Uyen would say* , I find this a teensy bit easier than Rotations. Because, unlike Rotations. This concept uses a Mapping rule.
and that mapping rule is . . .
( x, y) ▬▬▬► ( kx , ky )
"k" being that SCALE factor
simply put the number of time you multiply the x & y coordinates by to get (x , y) Primed

Let's say we have
[ ▲xyz ]
and the coordinates for the triangle were
[x] = (-2 , 8)
[y] = ( 6 , 2)
[z] = ( 4, -2)
and the scale factor is " 2 " or we want it TWICE as BIG
we multiply the X & Y by 2. so the coordinates for [ ▲xyz '] is . . .
[x'] = (-4 , 16)
[y'] = (12 , 4)
[z'] = ( 8 , -4)

try it on a grid . . .
[ ▲xyz ] is twice the size of [ ▲xyz ']

well, that's it for me. i gotta finish my map of atlantis. TAKE CARE ALL!!
KEEP IT RAWKING!

I miss you jellybeans :(

2006-03-17T15:40:00.000-06:00

Well, I will put it in writing...being sick sucks.

I am happy to hear that everyone is cooperating with the subs and finishing their work. It sounds like Mr. Tram will definitely be the next sub I call if I have to be away. I'm glad to hear that Jason has officially deamed Eric as smart. I knew that all along...that's why he frustrates me so much. I am very lucky to teach such a bright jellybean jar. I know that everyone of you is capable of amazing things when you put forth your best effort.

See you on Monday,
Ms. A

2006-03-17T14:01:00.000-06:00

We had a substitute teacher named Mr. Tram since almost all of us are done in our homework in page 306 he showed us bunch of cool games. The games that he showed us is the polar bears, the coins, and many more we had to try it but some of it are confusing and he showed a trick how to get the answer immedietly then someone will put three four digit number.

:P

March 16

2006-03-16T21:42:00.000-06:00

Woah! Today was the greatest, we had a substitute and his name was Mr.Tram. Lotta people were already done all their work, so Mr.Tram showed us a bunch of games. I don't really feel like taking the time to explain them all right now, but if you want me to tell you, just ask me at school next week.

And, um... Eric Everton is oficially smart now, he solved that back-spin puzzle game, if you don't know what that is, it's the game with the two sides and all the different colored balls and you need to put the balls in the right area. I was trying it for so long, then Eric just comes along and finished it. It only took him like...Two minutes. I'm so jealous.

Anyways, I gotta wrap this up so...I got one more thing to say

DON'T DO DRUGS!! It'll bring SLUTTEN FO DE!!

Sorry I coulnd't send in a post early because I didn't have the time to, sorry.
The day I was supposed to send in my post we learned alot of stuff like reflections where we have to reflect a given shape on a grid. We had to reflect by the given reflection line. Then we had to do some classwork-pgs.304-305,#1,#8-18 and #20-26.

Today in class we finished working on that transformation worksheet but if u did finish it in class it was for homework. We also did a transformation dance that a student made up. It was fun but Ms. Armstrong's dance was a little better then the student's dance.

2006-03-09T21:15:00.000-06:00

translating a shape or coordinate
talking about x- axis, the - sign means going to the left, and + sign mean going to the right..
y- axis, the sign - means going down, and + going up...

translate this in words(x-4,y+5)
word: x going to the left 4 spots, and going up 5 spots..

get it?
its kinda short, but easy, just like dancing too...

REFLECTION & REFLECTION LINE

2006-03-09T15:52:00.000-06:00

Today we learned new words and new stuff about the grid. Ms. Armstrong taught us on how to locate the reflection of a triangle by using the reflection line. We also did the grid dance.

Reflection or flip:A mirror image of an object without changing the size or shape.

Reflection line or mirror or axis of symmetry: Is the line which becomes the center of the reflected images.

CONGRUENT: the flower peddles are congruent because all (or maybe just two or three of them) are the same size and shape.

TRANSLATION: this diagram shows how shapes are moved from one point to another, which is called translation (but the triangles are also congruent because although they get moved over, they maintain the same shape and size).

2006-03-07T15:15:00.000-06:00

Today the class learned new words to help us on the booklet Ms. Armstrong handed out. Some of the words were mapping rules, quadrant, vertices/vertex, and congruent.

Mapping Rule: Give the direction of the translations. x -> is left/right and y -> is up/down. EXAMPLE: (x,y)-> (x+3, y-5)

Quadrant: one of the region on a coordinate grid, counter clockwise

Vertices-Plural/Vertex-Singular: The point where two lines meet or cross

Congruent: Two or more shapes that are the same size and shape. EXAMPLE: R and R = Congruent, but R and T are not congruent.

HI!! What Happened today!!!

2006-03-06T15:35:00.000-06:00

Hey you guys....I'm here again to tell you what happened today. Today we started reveiwing the how to move coordinates and how to write them.
For example. How do you write discribe the translation in words like (x,y)---->(x+3,y+4) the coordinates is x moves 3 to the right and y moves 4 up.
Then we learned how to move the shapes on a graph like
For example. The prime coordinates are A(3,2) B(-1,4) C(3-,5-) (x,y)-->(x-4.y+2)

How to do: Find the coordinates of A B C then when u do move them make sur to LABLE!!! like A1 B1 and C1
*EVERYTIME YOU MOVE THE COORDINARTE IT GROWS TO A LARGER NUMBER LIKE IF U MOVE A1 AGAIN IT TURNES TO A2

WEll THATS ALL 4 TODAY BYE TO EVERYONE IN THE WORLD!!

Whew! Dodged a bullet today. Mrs. Armstrong scared me, made me think the exam would be a walk through hell, but once I got the paper, it was a walk in the park instead. If you read the instructions, you'd know there was a bonus mark just for reading them, but I probably drew the worst sketch of Mrs. Armstrong in the WORLD!
So i thought it'd be hard, but it was easy. I probably beat all of you, so HA!

Today in class we had a substitute for Ms.Armstrong and it was Mr.Orstrander. He gave us a piece of sheet that showed us on how to review or study for the EXAM on FRIDAY. And 4 or 5 students read each point out loud. When that was done, he handed us a Mid-term Review Math Exam. We went in groups of 3 or 4 and worked on it. And that was mostly it we did in class...im pretty sure...but if not just leave a comment and yeah...=D

it was fun in class today

2006-02-28T22:40:00.000-06:00

HI GUYS, i just want to let you guys know how fun it was today in class
at first we start by playing a very fun,educative and understand
in relation to TRANSLATION and to be sincear with you guys i reald
enjoy playing .
then later on move to a new part of translating call MAPPING RULE
which was treaky at first but later on understand what she was trying to say.

DEFINATION;MAPPING RULE-it give the direction of the translation
x-is left/right
y-is up/down

2006-02-28T22:13:00.000-06:00

NOTE: if you dont remember how to work with integers ... then I strongly suggest you ask someone ..

-3 + 28

When working with integers, you should ignore the "plus" or "minus" signs , you should just think of all the numbers as positive and negatives. Positives mean "add on to.." and negatives mean "take away from.." , and when adding and subtracting integers you always take the sign of the higher number.

When multiply and dividing, the math is done normally but if the two signs are like same (+)(+), or (-)(-), the answer will be (+) positive. If the numbers are (+)(-), or (-)(+), the answer will be a negative.

-------------------------------------------------------------

Now to study the "Polynomials", "Powers & Exponents", and "Factoring"
This will be less complicated because these three units depend on eachother, and so if you know one , you`ll know MOST .

POLYNOMIALS

BASIC THINGS TO KNOW ABOUT POLYNOMIALS :

Expression - is the statement or question (problem) that is given

example : -3x + 10

Numberial Coefficient - is the number that comes before the variable (which is usually a letter)

example : -3x + 10
-3 is the number that comes before the "x" (variable) so therefore it's the numberial coefficient

Variable - it's usually a letter and it represents the value of an unknown number

example : -3x + 10
x is the variable, it comes after the coefficient

Constant : is the number that is alone, the one that has no variable beside it and stands alone as only a number

example : -3x + 10
10 is the constant

--------------------------------------------------------------------

TRANSLATING EXPRESSIONS -----

When translating expressions you should always circle and underline things to help you figure out the statement or to help you translate your expression.

examples:

The sum of a number and ten

How would you work that out ?

n 10
The sum of (a number) and ten

When you put it all together, you know its "the sum of" something so it's an answer to an addition (+), "a number" is the value of an unknown number so its a variable, and "10" which is a number ...

n+10

HERE ARE SOME QUESTIONS TO PRACTICE ON :

Three more than one fifth of a number

The quotient of ten and five multiplyed by a number

Triple the sum of six and a number

k well ... i`ll study some more math tomorow, like terms, BEDMAS, (dividing, multiplying, adding, subtracting) polynomials ... etc etc . hey this blog is pretty coooool . makes me so easy for me to study muuahahaha . math nerds , hey we should have a math nerds club chhyeaaah :D(Y) well im gona go study for social now HAHAHA . k LOVE YOU GUYS BYE :)

2006-02-28T22:02:00.000-06:00

Bet you guys didn't remember this ... because I didn't HAHAHAHHAHA ...

NEGATIVE CORRELATION : this scatterplot shows a relationship that drops to the right. The independent variable is increasing and the dependent variable is decreasing.

ZERO CORRELATION : The dots on a scattorplot are scattered at random and do not resemble a line

LINE OF BEST FIT : This is the line that goes through the middle of your dots to show you the relationship

INTERPORLATION : Basically means to estimate the value of something that is not already given on the scattorplot.

FOR EXAMPLE : If it said on a chart that the sales increased every 5 days, for 25 days, and you wanted to figure out how high the sales were on the 14th day. That would be an interporlation.

EXTRAPORLATION : is to estimate the value of something that is not already give on the scattorplot and goes beyond the highest value

FOR EXAMPLE : If it said on a chart that the sales increased every 5 days, for 25 days, and you wanted to figure out how high the sales were on the 27th day , thats an extraporlation

Exams

2006-02-28T21:12:00.000-06:00

Exams are coming up in a couple of days and I'm going to start studying for it. Although a lot of people may ask "How can you study for math?", actually you can and it's probably a wise decision TO study because then your awesome ! ;) But anyways, since I'm studying, might as well study with the whole class right ? Okie dokes.

These are the units we've covered so far:

Polynomials
Statistics
Powers & Exponents
Factoring

------------------------------------------------------------------

Basically the last unit we covered, Factoring, includes both "Polynomials" and "Powers & Exponents" (not so much Statistics though), so if you're able to do Factoring pretty good then you should be okay with the rest of the stuff.

STATISTICS

Since "Statistics" is the odd one, I think I'm going to start with that:

Statistics is more the "languauge" of math rather then numbers. You just need to know what each one means. This is how i summarized the unit ... you don't need to memorize the definitions, just need to know what they mean ...

WORDS YOU NEED TO KNOW ...

Population - is the entire set of items or group of people that data (information) can be taken from

EXAMPLE : If a teacher made a survey to see how many students would like to play basketball. The students are the "POPULATION"

Sample - is a selection taken FROM the population

EXAMPLE : If the teacher specifically picked Michele (me), and 5 or 6 other students. Those students selected would be the "sample"

Census - A survey that is based on the entire whole population, everything in the population is included

EXAMPLE : Canada has a census every five years where it surveys every adult in the country.

Representative Sample - A selection from a large group that portrays equally of the numbers of the large group

Bias - to apply either a negative or positive factor that could change an outcome, or that the whole population is not included.

EXAMPLE : Should teens be aware of the dangers of drinking and driving, to make our city a safer place ?
This question is bias, because it sort of pursways you to say "yes", because who doesnt want to be safe right ?

New Unit, New Life, New Topic

HELLO DMCI!!!
hahah. See? I actually got to a computer to do this post.
Well, what we did today was quite fun actually, we Practiced Plotting Co-ordinates on the Cartesian Plain by putting down letters on random coordinates on the Cartesian Plain that was marked on the FLOOR!!! Well, I disagree with Mrs. Armstrong.. The class didn't smell that skunky! You should go inside the Boy's Locker Room after GYM!!! Well, apart from that we Did The Three point approach Sheets.

-------------------------------------------------------------------------------------------------
Word = Co-ordinates
Defenition = An ordered pair that locates a point on a Cartesian Plain
Synonym = Ordered Pair
-------------------------------------------------------------------------------------------------
Word = Translation
defending = Sliding a figure (Shape) up, down or diagonally along a straight line WITHOUT changing it's size, shape or orientation.
Synonym = Slide
-------------------------------------------------------------------------------------------------

Well, That's about it.
I Have to go now.
REMBER KIDS!!

Hey folks, it's Kyle again using my bros. account, still can't figure out my password -_-' but heres what we did today Mrs. Armstrong gave us 20 minutes to finish up our test. She then gave back our setting goals, sheet along with another sheet. Then we filled out new setting goals sheet, and also learned new words, tautology. I think thats the right spelling, it should be right i used spell check =D.

Try This!!

factoring :D

2006-02-21T18:48:00.000-06:00

today in class we did this work sheet on factoring numbers and were assigned to do all the even question numbers. We also did a hangman to find out the method that we are supposed to use for it which is the grouping method. Oh and Mrs. Armstrong also spelled method wrong hehe but its cool I forget how to spell a lot of words too.hmm what else did we do?? Oh and I was chosen for scribe today as you can see. Anyhow the work sheet we were assigned has questions like 2a squared +5a+2 the way you do this question is by first multiplying the first number by the last number ex: 2x2=4 then you factor out 4 ex: 4=2x2 and 1x4 then you find the mulitiples that equal to the second number when added ex :in this case it would be: 1x4 then youadd it into the question ex: 2a squared +1a+4a+2 then you find the GCF for both parts of the question ex: 2a squared +1a =1 and 4a+2=2 then you put it into brackets ex: a(2a+1) 2(2a+1) then you take what is in side the brackets and what is multiplying the numbers in the brackets and you multiply them together useing brackets ex: (2a+1)(a+2) and this is your answer. well yha ok see you peoples!

Michelle.S pretty much said everything...we had like this mini-quiz...and then got into groups of 2 or 3 and went through every question explaining how we got the answer....the assignment was pg.22 of the green booklet

yesterday's class

2006-02-18T16:43:00.000-06:00

sorry I didn't get to post up what we did yesterday because I was not able to log in. anyways in class we had to answer five questions . . . sort of like a quiz but instead of getting our answers checked for marks we were given cards. with those cards we were assigned to groups of twos or threes. we then had to discuss the question given to us and write and explain our answer as a group to the rest of the class. if our answers were discripted enough and right then we would receive full marks. our questions were based on finding the length and width of a rectangle and the area. anyways for those who are in my class . . . the assignment' s page 22 in the green booklet.

What we did on Feb.15/06

2006-02-18T12:21:00.000-06:00

Today all we did was got in to our groups. Worked on a group problem our problem
was the yard b on the group problem sheet. Corrected page 19 in the green booklet
and i'm finally doing my work in class now becuase i know what to do now. LOL!!

Hey Jellybeans,

Is this cool or what??? You can make your own graffiti art using this site, GraffitiCreator.Net (It is super easy to use)

I found out about it from GraemeW in Mr. Malandrakis's 20s Computer Science class.

Ms. Armstrong

Are you up for a little challenge???

2006-02-17T17:26:00.000-06:00

Hey Jellybeans,

Think you're pretty good at this scribing thing?? Check this out. This is a scribe posting from the Pre-cal 40S class. Pretty impressive don't you think. Why not try to challenge yourself and aim for this quality. It shows great attention to detail and demonstrates a firm grasp of the content.
I know that you can do it.

Ms. Armstrong

Now for something completely different :)

Place the digits 1, 2, 3, 4, 5 and 6 in the boxes (one in each), so that the multiplication is correct.
How many solutions can you find? Can you explain how you found them?

The poles where the rings land are multiplied. For instance, if you throw 5, 7, and 11 twice, your score is 5 * 7 * 11 * 11 = 4,235. Can you figure out how to score 3,168?

F.O.I.L

2006-02-15T19:29:00.000-06:00

Today we learned a new, and easy way to multiply with binomials using FOIL.
F = First O = Outside I = Inside L = Last

eg. (h - 7)(h - 8)

First = (h - 7)(h - 8)
= h² - 8h - 7h + 56
Outside = (h - 7)(h - 8)
= h² -8h - 7h + 56
Inside = (h - 7)(h - 8)
= h² -8h - 7h + 56
Last = (h - 7)(h - 8)
= h² -8h - 7h + 56
_________________________________
= h2 - 8h - 7h + 56
= h2 -15h + 56

That's how easy these problems can be using FOIL. After Ms.Armstrong showed us how to use F.O.I.L. she handed each of us a card. Where one person would read an expression, and another person would say "I HAVE" if they have the answer to the question. Then they would say what they have, and turn the card. And then they would say a question themselves and someone else would now have to say what they have.. and so on and so on. It's a pretty fun game we should play it more often, Ms.Armstrong. =D

MERRY VALENTINES!

2006-02-14T20:02:00.000-06:00

i have always wondered what valentines day was about... so i decided to search it up.. and it turns out.. it started from the war of love and anger.. check it out.

"Legend has it that the original St. Valentine was a priest in Rome during the reign of Emperor Claudius II. Claudius was a vile and brutal ruler bent on amassing an enormous army. To achieve this, he banned all marriages in case husbands refused to leave their new wives and go to war.

Enter he whom I consider was the rather romantic St. Valentine, a priest who cherished love over war and clandestinely married enamoured couples. For his kindness and compassion, the quixotic priest was bludgeoned to death and beheaded on the 14th February 269 AD on the order of Claudius."

hehehe.. great story.. anyways... TO ALL MY FRIENDS!!! HAPPY VALENTINES!!! TO MRS. ARMSTRONG... HOPE YOU HAVE A GOOD ONE WITH MR. ARMSTRONG..

Distributive property???????

Factoring Polynomials

How do I format an exponent?

2006-02-14T15:50:00.000-06:00

Hello Jellybeans,

I thought I might be able to help out with the ever annoying exponent problem. Instead of typing 48x^2, you can use a little html code to create the exponent. To do this, just type 48x2 and then click on the 'Edit Html' tab at the top right of the composing box. Type the code <sup> before the exponent and the code </sup> after the exponent.This will raise it up. I have to give credit to Danny T. who showed me how to do this. That's the beauty of blogging - everyone is teaching everyone :) If you have a few spare moments, why not pop by some of the pre-calculus or consumer math sites to see what you will be learning next year. While you are there, leave some encouraging feedback for them. They would love to hear from you.

Ms. Armstrong

My Apologies

2006-02-14T15:05:00.000-06:00

Dear Bloggers,
About two weeks ago I made a poor choice. I should've written this letter earlier but it's not the easiest thing to do.

An inappropriate comment appeared on Ms. Armstrong's class blog. The language in that comment was very rude and affected my teacher, my classmates, my friends, my school, and myself. I need everyone to know that is not who I am. I did not think that I was using the class blog and thought I was using my friend's. Regardless, there is no excuse for my behaviour in terms of how I chose to use the internet.

The internet as you all know is a great tool to communicate, do research, and keeping in touch with the world. I abused it and learned a tough but valuable lesson. I hope my experience will prevent others from making the mistake I did.

I just want to apologize to my teacher, my classmates, and my school for what I've done and I will never abuse the use of the internet again.

Sincerely,
Andrew

Same as yesterday's yet this time with negatives.

2006-02-13T21:18:00.000-06:00

all we did today was the sheets that arvin didnt finish... nice going.. and we went on to the next part of it. This time it's with a twist, there are negatives...

if the question was..

x^2 + 12x +20
it would be equal to...

(x + 2) (x+ 10) = x^2 + 10x + 2x +20 = x^2 + 12x + 20x

this time... we did it with negatives...
find the factors of..

x^2 - 12x -20

it would be equal to...

(x - 2) (x + 10) = x^2 -10x -2x -20 = x^2 -12x -20

now now now... how did i do that?
hmm.. because + times - is = (-)

:P
i guess now i did my part... so i'll leave it to that..
Remember to do that pages ms. armstrong told us to do.
the Whole page 20 i think..
CYA!!

I don't know about uyen but at least i did my share

Polynomial Games - A review for factoring

2006-02-13T11:00:00.000-06:00

Hey Jellybeans,
I've found some great polynomial and factoring videos for you to use if you are stuck. Just click on Chapter 5 or 6 and choose the topic that you need some extra help with.

I also found these games for you to try.

Multiplying Polynomials - Who wants to be a millionaire
Polynomial Jeopardy - This is a terrific game
Combining like terms
Polynomial identification
Evaluate the polynomial
Add or Subtract polynomial

Keep playing these games even thought the 'polynomial unit' is completed. They will help to strengthen your skills for 'Factoring', 'Powers and Exponents', and 'Linear Equations', not to mention the exam. REMEMBER: Just like integers didn't go away when you finished the formal unit, neither will polynomials. Math is about building a strong foundation and understanding so that new topics can be understood and learned.

Ms. Armstrong

Need some help in math? Well look no further cuz these links can help you

2006-02-12T16:19:00.000-06:00

Wassup guys just found some new links to some math games.
link 1 lol this website's games are easy. You could check the other games in this website too.
link 2-this website is kinda cool and complicated too. It helps make solving polynomial problems easier, not that im saying that polynomials are hard for you guys, it just helps you if you are stuck in any problems plus Mrs.Armstrong does a good job in explaining polynomials. I don't think you guys would need to visit this site if you listen properly in class, lol not that I'm saying that you guys don't.
Sorry but i couldnt find anymore websites for you guys these to links were the best that i could come up with.

Factoring and Time Travel - all in a day's work

2006-02-10T17:43:00.000-06:00

Hi!!This is what we did today.Well we did more of the factoring bingo.(you would have learned that we did that yesterday, but yesterday's scribe didn't do his job). We also learned why Ms. Armstrong played bingo with us: She did it to show us a preveiw of what we learned today:Binomials by binomials. Like x² +9x +20=(x+5)(x+4).x²+5x +4x +20= x² +9x +20. Also, for those of you who wheren't there on Tuesday, I learned a new arithmatic term: Tessaract. 4dimetional. You can't make a visual representation of it because, even though we live in 4 dimentions, we only see 3. You're probably wondering what the 4th dimension is: It's time. To make one you'd have to go back in time which you can't because times a constant not a variable.Unless there was a spacial annomoly to send you either through time or the opposite. Do that you've got yourself a tessaract.

Research Director - A new hat to wear!

2006-02-09T20:10:00.000-06:00

Hello Jellybeans,

Starting tomorrow morning we will be adding a new daily feature to the blog. Each day the "Scribe" will choose a "Research Director". That person's job will be to search the net for a great new math site that helps to explain, reinforce, or extend a topic that we have covered in class. The Research Director will post a brief summary of the site, and share it with the class by creating a link.

Since most people prefer to learn from visuals, try looking for videos, diagrams, or java applets that demonstrate a topic really well. Maybe you can find a neat cartoon or powerpoint. You never know what you might find. Don't forget to credit the author of any material that you borrow. Just because it is on the internet, does not make it yours to take. One day someone may borrow intellectual property that you created - wouldn't you want them to at least recognize the efforts that you made???

Happy surfing!
Ms. Armstrong

Psychic, psycho or telepathetic???

2006-02-09T12:40:00.000-06:00

Hey Jellybeans,

Thanks to Jason D. I have a new word - "Telepathetic" - I like it, it's good. Anyways, check this out and then check this out. See if you can find the "pattern". After all, if it's math, there has to be a pattern.

Factor: 2 or more numbers multiplied together to give a product.

Example: 8 x 2 = 16

Find the Factor:
1) 16 = (1, 2, 4, 8, 16)
2) 12 = (1, 2, 3, 4, 6, 12)
3) 10 = (1, 2, 5, 10)
- The GCF (greatest common factor) is 2

YOU CAN GET THE GCF USING FACTOR TREES

1) what is the GCF of 36 & 42

1)
36
=
6x6
=
3x2 x 3x2

2)
42
=
7x6
=
3x2

THE GCF IS 6

Today we corrected the "A Little Quiz" quiz.

Sarah insisted that there were errors in the following statements. Scott insisted that the following statements are correct. Who is right and why? Correct each statement that has an error(s).

Here are the correct answers :

1. (x^8)(x^4) = x^32

- this statement is wrong

- (x.x.x.x.x.x.x.x)(x.x.x.x) = x^12
(^eight "x"s and four "x"s equals twelve "x"s)

- it is product law

2. (b^2c^3)(b^3c^2) = b^5c^5

- this statement is correct

- (b.b)(c.c.c) . (b.b.b)(c.c.c) = b^5c^5

- it is product law

3. (a^2b^3)^5 = a^10b^15

- this statement is correct

- (a.a)(a.a)(a.a)(a.a)(a.a)(b.b.b)(b.b.b)(b.b.b) = a^10b^15

- it is power law

4. (-3mq)^2 = -6m^2q^2

- this statement is wrong

- (-3mq)^2 = -3mq x -3mq = 9m^2q^2

- (-3)(-3)(m)(m)(q)(q) = 9mmqq ^^ like shown

- first of all 3x3 is not 6 , the person who made this statement added the two 3's instead of multiplying them. 3x3=9 , and a negative number multiplyed by a negative number equals a positive number, not another negative. But they added the exponents correctly

- it is power law

5. (2k^2g^3)^4 = (4g^6k^4)^2

- this statement is correct

- (2)(2)(2)(2)(k.k)(k.k)(k.k)(k.k)(k.k)(g.g.g)(g.g.g)(g.g.g)(g.g.g) = 16k^7g^12
(4)(4)(g.g.g.g.g.g)(g.g.g.g.g.g)(k.k.k.k)(k.k.k.k) = 16k^7g^12

- it is power law

6. (3a^5b^6c)^2 = 3a^7b^8c^3

- this statement is wrong

- (3a^5b^6c)^2 = (3)(3)(a.a.a.a.a)(a.a.a.a.a)(b.b.b.b.b.b.b)(b.b.b.b.b.b)(c)(c) = 9a^10b^12^2

- it is power law

NOTE: all of these statements are "exponent" laws . There were a lot of people who lost marks by putting "exponent law". PRODUCT LAW, QUOTIENT LAW & POWER LAW are all under the catagory "exponent law"

Then we spent the rest of the class correcting (in groups) the "Following the Directions" sheet. The end answer was "Lemons For Sale", but you need to do all the work in between to figure out how that was done ...

WELL TODAY WAS EARLY DISMISSAL SO WE DIDN'T DO MUCH . SEE YOU GUYS TOMOROW

DUE : POWERS AND EXPONENTS UNIT DUE !! HAND THAT IN A.S.A.P. (:

Hey Jellybeans,

Here is a link straight from Sargent Park that you MUST check out. Mr. H. has posted some really great brain puzzles for you to solve.

I also thought you might want to check out the grade 8 blogs that you have inspired. I'm sure that they would love it if you left positive comments to encourage their blog to grow. You can also invite them to check out some of the work that you are most proud of. Just think...you can be a mentor for next year's S1 class before they even get here!!!

I don't want to do this

2006-02-06T15:57:00.000-06:00

ok this is what we did today
-we talk about some coures we can take later on
-we got some test back
-we did a little work and some work in the book pg-191 #25 I got the answers but I just hope I don't forget them
and that a quick review on what we did for today

U TRICKED ME!!

2006-02-03T22:02:00.000-06:00

WOW!!! we are actually DONE with half of the school year... and that makes me both sad. and happy... take a biiigg guess why.. :P
anyways...
TODAY... was very very very..very.........VERY.... confusing... if it wasnt for my friends to guide me around. i would have been marked absent for most of my subjects... im too used to my semester one subjects.

MRS. ARMSTRONG!!! she made us do this quiz that had all these questions.
number 1 was "read all questions carefully before doing anything" emphasize on the ALL questions part.
i did it all and when i got to the last one... BOOM! it said "do only questions one and two."
AHHHHH!!! i multiplies a 3 digit number by a three digit number without a calculator! hmph.

well.. moral..
"READ BEFORE YOU ANSWER!"

hahhaha... NICE ONE mrs. armstrong!!

wel i guess that's it.. if i'm missing any or made a mistake just leave a comment or something then i'll edit it !! hehehe..by the way ... its due on the 6th of febuary.. i think .. well I need to study ... later people :P have a great weekend :P

Anne u better look at dis!! :P

well since im on da blog already ill explain some stuff that we learned so far....

exponential form

- a short hand method of writing #'s expressed as repeated multiplication

example:6 ¹²

expanded form

- repeated multiplication of a base

example: 3x3x3x3x3x3

standard form

- the usual way we write a number

example: 8

base

- the number used as a factor for repeated multiplication

example: 6 ¹² 6 is da base

exponent

- the raised number that tells you how many times the base is repeatedly multiplied

example: 6 ¹² 12 is da exponent

product law

- to multiply powers with the same base then add the exponents

example: (x²)(x³)= x⁵

quotient law

- to divide powers with the same base then subtract the exponents

example: x⁴÷x³= x¹

reciprocal

- a reciprocal is a fraction that is flipped upsidedown. we use it when we have a negative exponent

example: 7^-2 = 1/49

power law

- to raise a power to a power,then multiply the exponents

example: (7³)² = 7⁶

zero exponent law

- anything with a zero exponent is equal to 1

example: 10⁰ = 1

that's it for now people.. i need 2 study .. hehehehehe..

hopefully someone will actually read dis...

not sure if i explained it right :S..

hehehehehe .. oh well...

u better study anne ..... :P

juzz lve a comment if u guys dont get it ok ...

later

2006-01-26T20:48:00.000-06:00

hey guys i want to say i like this blog.......
and i like the teaching of miss armstrong....
like the exponent and power thats the lesson that i love too learn

guys sorry for my english because i have a problem with that but

i learn from miss armstrong that math is not a hard subject

so miss Armstrong thank for that wonderfull tym with us

thank miss Armstrong!!!!!!!

hey guys!!!

2006-01-25T21:11:00.000-06:00

hey guys how are you? i dunno how to keep in touch with many of you so i decided to post on our blog...if you guys don't know i'm in Philippines right now. and guess what? it's WARM here=P
hahhaha. There are 2 reasons why i posted here, one is i need help! I missed most of the power and exponent unit so i need you guys to tell me what i should study for the exam. Just go on the commnet box okay?i'll update and read your comments if there's any...
well bye guys.god bless and take care always.
Oh yeah the second reason why i posted here it's to tell you guys that...

New Game - Circle 0

2006-01-24T15:22:00.000-06:00

click here to play this game.

The goal of this puzzle is to put three numbers inside of each circle so that they add up to 0.

Solve the puzzle by dragging the black numbers to the blank spaces. You cannot move the blue numbers.

When the three numbers inside any circle add up to 0, the circle changes color.

Thanks to Mr. H and Sargent Park's Grade 8 Math Zone for this great puzzle.

If you want more puzzle's that are similar to Circle 0 - Try Circle 21 or Circle 99 for a challenge

scribe

2006-01-20T19:48:00.000-06:00

well, this is actually a scribe for thursday, i think. first off we just tried and played around with uyen's puzzle and nobody could get it. the best pieces i could get is 7. after that we got assigned pgs.39 #'s 69,70,78 and 79, and pg.38 #'s 1-47. that's it, so, don't do drugs!

What We Did Yesterday...

2006-01-19T16:02:00.000-06:00

Today we corrected our worksheets on using the quotient law, and using the zero exponent law. If you guys are having trouble remember to STOP! then expand, then it'll be easier for you to solve, or evaluate. Once we finished correcting those worksheets, Ms.Armstrong gave us a 10 question quiz on quotient law to see if we really understand what to do. Then after all those correcting we did more work on pg. 39 # 69,70,78,79.

the day b4 yesterday

2006-01-18T23:07:00.000-06:00

Well this i is kinda late but w/e..So, on Tuesday, January 17th, we learned about the Quotient Law and the Zero Exponent Law.

Quotient Law-To divide powers with the same base, subtract the exponents.

If the basse is a avriable with a numerical coefficcient-- dividethe numerical coefficients(using the integer rules.), then divide the powers.

Zero Exponent Law-Any non-zerobase raised to the exponent zero is equal to one.

If you are ever unsure of a law-STOP!!-Write the question out in expanded form and then look for the pattern.

HAHA SCRIBE!! and a brain teaser!! haha

2006-01-18T17:10:00.000-06:00

HEYY!! ppl here is my scribe 4 today haha

We reviewed the Zero Exponent Law and the Quotent Law. Marked the 2 math sheets from yesturday which was home work but w/e we maked them to mark the text book pages from yesturday which was homework u have to look at the answer key in the bac of the book...

TODAY ASSIGN: Pages 39 #69, 70, 78, 79
Pages 38 # 1-47

* NOTE: do page 39 first before doing 38 KK!! ^_^

MY BRAIN TEASER!!!

You have a pizza and u have to make 8 equal slices but u can only use 3 straight cuts ONLY!!! if u have an answer comment kk!!!

*NOTE: Ms. Armstrong didn't solve it yet haha......

THings That we Did TOday

2006-01-16T20:02:00.000-06:00

Working With Negative Bases

Evaluate (standard form)

Positive Bases:

2²= 4

2³= 8

2⁴= 16

2⁵= 32

Negative Bases:

You can write this in expanded form

-2²= -4 -2x2 or 2x2x-1

-2³ = -8 -2x2x2 or 2x2x2x-1

-2⁴ = -16 -2x2x2x2 or 2x2x2x2x-1

-2⁵= -32 -2x2x2x2x2 or 2 x2x2x2x2 x - 1

Negative Bases with brackets:

(-2)²= 4 -2x-2

(-2)³ = -8 -2x-2x-2

(-2)⁴ = 16 -2 x-2 x -2 x-2

(-2)⁵= -32 -2 x-2 x-2 x-2x-2

Using your brains!! 5x5 = 25 , 5x5x5 = 125

Here's an example:

5²= 5x5 = 25

-5²= -1x5x5 = -25

(-5)²= -5 x-5 = 25

-(5)²= -1x5x5= -25

-(-5)²= -1x-5x-5 = -25

~~~~~ Get it so far?? Well then you should try it !~~~~~~~

5³=
-5³=

(-5)³=

-(5)³=

-(-5)³=

Dividing bases:

Exponential form:

Expanded Form :

Answer in Exponential form :

Answer in Standard form:

2⁵÷2²=

3⁴÷3²=

10⁵÷10=

7⁵÷7⁹=

4²÷4⁶=

7⁴÷7⁴=

3⁵÷3⁵=

2⁵÷2²=

dont know what to do?? well here's an example. Then do the rest for homework !!

2⁵÷2²

expanded form:
2x2x2x2x2

2x2

Answer in exponential form: 2³

Answer in standard form: 8

any questions?? leave a comment and i'll try to answer it for you!

SCRIBE FOR THE DAY ONCE AGAIN!!

2006-01-16T18:05:00.000-06:00

Today in class we learned how to work with negative bases. The negative base is similar to postive base in powers. The thing with negative bases that if the power has a negative infront of it. -2² the product would automatically be a negative. The answer isn't a postive for you people wondering why it is a negative. The reason is you are multiplying a negative number to a postive number which will turn it to a negative answer. (-2 x 2) = -4. If your working with exponents like 99,5,63. The product will always be a negative. You always have to multiply with a negative number first than a postive number. Example: (-2 x 2 x 2 x 2...)

The other way with negative bases you might get a question like example (-2)². The way you do this question is that you multiply with the same value with a postive or negative number value. So to do this question it is (-2 x -2) = 4. Remember if the exponent is an even number it will be a postive answer. If the exponent is an odd number it will be a negative answer.

A helpful hint: The exponent is only applied to what is directly in front of it.
Example: -5⁴ means that the exponent is only for the 5 NOT the negative. In expanded form it would be -1 x 5 x 5 x 5 x 5 = -625
Example: (-5)⁴ means that the exponent is applied to the entire contents of the bracket. In expanded form it would be -5 x -5 x -5 x -5 = +625

We also learned to divide powers. Diving powers is pretty straight forward. If you have the same base with different exponents you just subtract the exponents and keep the same base number. Example: (2³ ÷ -2²) you keep the base which is 2 and you just subtract 3 - 2 which equals to 1. The final answer is 2¹

------------------------------------------------

Powers with Negative Base Tips:

Just remember if you get a question like....

2² in expanded form: 2 x 2

-2² in expanded form: -2 x 2

(-2)² in expanded form: -2 x -2

-(2)² in expanded form: -1 x 2 x 2

-(-2)² in expanded form: -1 x -2 x -2

A Maze Game with a Twist

2006-01-15T08:46:00.000-06:00

Hey Jellybeans,

Here is the latest game that I came across for your enjoyment. It is called Slither Link and it's a combination of the game 'dots', mazes, and strategic thinking. You will really need to think ahead a move or two to do well on this one. You may also have noticed that I have rearranged the side bar on the right. All of the games that I posted earlier this year are now easily accessed under the heading of Games and Mind Benders. Just click on the title and have fun.

Ms. Armstrong

Jan.12 Product Law

2006-01-14T20:40:00.000-06:00

Discover Exponent Law

Part : 1
example: 4^3 + 3^4 = 145
4x4x4 + 3x3x3x3 =
64 + 81=
145

Product Law - To mutiply powers with the same base add the exponent.
example: (x^4)(x^2) = x^6

If you are ever unsure of the law - STOP! Write the question in expanded form and then look for the PATTERN

a really really late response,

2006-01-12T15:24:00.000-06:00

Hi,for those who missed our lesson for math today...
here ,
im doing it with my own wordz
We learned about census and sample....
Census means a survey or all the members or group and no one would be left alone, while sample is just picking what they want..example for census:
The cafeteria at your school sends home a SURVEY with every studentto determine if food prices are affordable..
.example for sample:A mother tests the temperature of a baby's formula by touching a few drops on her wrist
I'm not tht good in explaining,but ill do my best next time...Hope you guys understand...
