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?

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

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

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

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.

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.
