Editting - The Greatest Challenge

Hello Jellybeans,
I am very impressed with the posts you have been leaving for one another. Now we must come together to improve the accuracy. Who dares to accept the greatest challenge? I know that YOU will (because it's for bonus marks). Thanks to Mr. K for the terrific job working out the editting details.
Step 1: Scan through the previous posts on the blog. Find one that has one or more errors.
Step 2: Discuss the error(s) and what you think the correction(s) should be with me.
If I agree with your editorial proposal go to Step 3.
Step 3: Discuss the editorial change with the author of the post. The author will chose to proceed in one of the following two ways.
Option A:
The Editor is briefly allowed administrative privileges on the blog. They will edit the post to make any necessary corrections. They then sign the post at the bottom: Edited by: [name] on [date]
Option B:
The author will edit the post in consultation with the editor who will vet the author's changes until they are correct. The author then signs the post at the bottom: Consulted editor [editor's name] on [date]
Students may chose to make more than one edit. Each additional edit will earn them a bonus mark on the next test. Your mark on the previous test determines the maximum number of edits/bonus marks available to you.

Mark on Last Test / Max Edits Allowed
> 90 / 1
80-89 / 2 (1 bonus mark)
70-79 / 3 (2 bonus marks)
60-69 / 4 (3 bonus marks)
50-59 / 5 (4 bonus marks)
40-49 / 6 (5 bonus marks)
30-39 / 7 (6 bonus marks)
20-29 / 8 (7 bonus marks)
10-19 / 9 (8 bonus marks)
0-9 / 10 (9 bonus marks)

You may also assume the role of Content Consultant to earn marks as outlined above. Here's how it works:
Step 1: Scan through the previously posted Scribe Posts on the blog. Find one that doesn't provide enough detail or leaves out too much information. Decide what additional content should be added.
Step 2: Discuss the new content you think should be added with me. If I agree with your editorial proposal go to Step 3.
Step 3: Discuss the editorial change with the author of the post. Together, you will chose to proceed in one of the following two ways.
Option A:
The Content Consultant will add a new post to the blog inserted at the appropriate time and date. They then sign the post at the bottom: Additional Content by: [name] on [date]
Option B:
The author will edit the post to include the additional content provided by the consultant. Additional content will appear under a heading "Additional Content". The author then signs the post at the bottom: Additional Content Provided by [consultant's name] on [date]
Students may chose to make several additional content contributions for bonus marks according to the table above. You cannot edit your own posts. When it's your turn to be scribe try to write a post that is so excellent that no will be able to edit it. ;-)

Math class was pretty good i finally sat on the other side and it's way better for some reason? well summarized the candy contest and drew images of it. Did a worksheet and we had to arrange different statements on whether it was a census or an example, that's pretty much all we did.

Please Join my S1 Math Forum(currently underconstruction)

http://s13.invisionfree.com/DMCIMath/
I'm currently working on a math forum... I like using forums better than blogs so yah..
I also need help moderating and stuff for this forum... email me if your interested. avelinoe@mb.sympatico.ca


cont'd
In a forum you'll be able to discuss things. Right now I have topics which I copied down from the Common Course Outline Mrs. Armstrong had handed out to us in the beginning of the year. If you need help on one of those topics, post what you need help with and somebody will try to get back at you by replying.

Hee, Hee, Hee... oops!

You are absolutely right Daureen! Way to check up on that Arvin!

The only thing is, I meant to write

x(7x^3+x^2+5)

So, if you subtract x(2x^2) where x=3 from Daureen's answer, you'll finally "be in the know."

By the way, do you remember that T.V. commercial with the boy who kept on changing all the chocolate chips in cookies to rainbow colored chips? Everytime he did, he laughed "hee, hee, hee, oops!"

How many candies filled the jar?

Good afternoon jellybeans!

And now, the number you have all been waiting for... [drumroll please]...

x(7x^3+3x^2+5) where x=3

...so close to the truth! Who will accept this challenge? :0)

I learned a lot from teaching both classes on Friday especially that the last period on a Friday afternoon is one of the most difficult to manage because students seem to be high energy, excited about the weekend, and teachers seem to be low energy after a long week of hard work. I'm open to some suggestions as to how to make next Friday work.

Hope you all had a great weekend, and I look forward to exploring "statistics" with you more over the next four weeks.

Statistically speaking

Hello again Jellybeans,
Here are some games to help you study the new vocabulary that Ms. Nicholson introduced for the statistics unit.

Sampling Terminology
Graphing Terminology
Scatterplot Terminolgy

Keep practising... you are going to be very smart mathematical jellybeans.
Ms. Armstrong

You asked for more games...so here they are!!

Hey Jellybeans,
I've been checking around for some more math games and I found some great logic puzzles...just like you asked for.
Check out these sites and let me know what you think.
Stamp Puzzler
The Puzzle Beast

If 'number math' is more your thing, I've found some great polynomial games for you to try out.

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

Keep playing these games even thought the 'polynomial unit' is completed. They will help to strengthen your skills for the 'Powers and Exponent' unit and 'Linear Equations' unit, 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.

See you on Monday,
Ms. Armstrong

Today in Class

Hmm....today in class we were learning or actually playing a game about stat....ist....ic....yes statistic. And it was fun cause the first game we had to guess how many candy were in the candy jar, and at first we didn'y know the type and size of the candies, only we knew how big the jar was. So we had to make a guess. And then later some of the students received jellybeans and some m&m's and there were twice as many m&m's then jellybeans, and that was a clue. And when I saw the sizes of the candies my whole answer changed. So once Miss Nicholson showed us the jar filled with candies, and we had to submit our guess, the winner who guessed was close was Ahmad......=/.........So for the second game we just had to go walk around the class to look for definitions on the walls and write them down. It was a bit fun and hard cause you have a partner and one will run up to the definition and read and come back remember some of the sentence they had read and the other person will write it down. And onces that is done, you switch spots and the person who wrote does the running and reading, and the person who did the running now does the writing part. And that was mostly it, and I think we don't have any homework......=/

(wow I wrote alot....=/.....this rarely happens....but ehh)

Ryan R. (rayan)

today

played a math board game with the two edwards, celeste, and michelle it was okay, there should be new games though. have to work on arranging my polynial unit together now

.....THE MATH BET....

daureen and i made a bet of one dollar on who get's the higher mark..
i bet taht sh'ed get higher but she bet that i'd get higher...
it's $1 on the line!! hahahaha
the math test was easy.... not to be boastful... but it was esay.....
TAKE CARE ALL!!!
cya at class tomorow!!
remember!! it's careerday...
hhahahahah





"the world parts for a man who knows where he is going"
-anonymous
this means.... follow ur dreams!! TAKE CARE!!

Ryan's 3 guestions?

1. -3a(4a+8b)+5(8a+5b-10)

2. A number that is multiplied by six, but shared equally with four people.

3. (4x)(5y)-9x(7x-8y) x=5,y=2



The Answer


1.
-3a(4a+8b)+5(8a+5b-10)
-12a^2-24ab + 40a+25b-50

Answer
-12a^2+40a-24ab+25b-50


2.
A number that is multiplied by six, but shared equally with four people.

Answer
6(n)/4


3.
(4x)(5y)-9x(7x-8y) x=5,y=2
20xy-45x^2+72xy

20(5)(2)-45(5)^2+72(5)(2)
20(5)(2)-45(25)+72(5)(2)
20(10)-45(25)+72(5)(2)
20(10)-45(25)+72(10)
200-45(25)+72(10)
200-1125+72(10)
200-1125+720
= -205

Answer
-205

A faster way of doing it

20(5)(2)-45(5)^2+72(5)(2)
20(10)-45(25)+72(10)
200-1125+720
= -205

3 questions

1) (4m)(5n) = 6mn
2) -4x + 10
10x - 18
_______
= 14x +2
3) 3 + 9b + 10 = 13 + 9b

.. i don't know if they're right though

Are you studying???

Hey Jellybeans,
Here's a study tool to help you prepare for the polynomial test on Wednesday...yes, you have a test on Wednesday.

Create 3 questions that you think I might ask on the test. (Try to be tricky and stump your friends). Post those questions on the blog and let your classmates try to answer them in the comment box. On Tuesday, you can edit your post and show the solutions to your questions. I will award 2 bonus marks on this test for each original question, and accurate solution that are posted. (Maximum of 6 bonus marks on this test)

Here are some practise questions to get you started.

1. Using the diagram, explain how the algetiles represent the process of subtracting polynomials.

2. Find the area of the diagram to the left. <---

Feeling confident...feeling smart...up for the next challenge...

3. Find the perimeter of the same figure (Hint: you will need to find out the lengths of the 2 missing sides - if you get stuck, try doing the same problem using natural numbers and then use that problem solving technique with the polynomials.)

Good Luck and have fun studying with one another :^)

i was soo bored on saturday night i started playing on the games posted on the s1 math site till five in the morning Hahahaha.

Inspirational Jellybeans???

Well Jellybeans, you are not only teaching your classmates, but have inspired your Vice-Principal, (the one, the only, Mrs. Silva) to join the blogging community. She has been so impressed with your classroom reflections and mathematical journeys that she has started her own blog. Check it out and don't be shy to leave encouraging comments for her.

You should be very proud of yourselves.

Ms. Armstrong

....The "Silva" Challenge....

you want math ms. silva??
well.. it's 6:12 pm..... i'll jus give a brief explanation to what we did today..
we learned... substitution... no.... not the substitution in a basketball game...
my defenition of substitution is...
"substitution is simply, giving the variables in a polynomial a certain value"
sound simple...
it really is..
hehehe ... here we go..


say we play a game....
in this "game" we start off with 50 points each...
and for every correct answer we get... we get 3 points...(each correct answer i get is represented by a x)

so.. our starting number of points is 50... now this never changes....
we ALWAYS start with 50... so this "50" is our constant...

then.... say i got ten correct answer.... to get how many points i have..
this is what i was taught to do...

10 x + 50

10 x means i got TEN of x..... now... to get how many is 10x... this is what we do

how many did i score? = 10 ( <--this is how many i scored)
how many points per score? = 3 (<--this is what the x means.)

so.... i multiply it.... 10 (3) = 30

now i know how many i scored..
30.... and i started with 50... so i add that...
30
+ 50 (<--this is our constant.. the number of points we started with...)
= 80

simple ryt?
aight... i gtg....(got to go.)
take care all!!!!
buh bye!!

oh yeah... leave a comment... please?
heheheh
i'll give you a cookie..
:^)

PEACE!!

Another puzzle from Mr. K.

Hey Jellybeans,
Want another puzzle to mess with your heads??? Check out Mr. K's blog. He puts up a new puzzle every Sunday. Check it out and let me know if you figure it out.
Ms. Armstrong

Sunday Fun! (or Sunday Madness)

Hey Jellybeans,
As long as you're here....why don't you check out Mr. K's grade11 and grade10 precalculus blogs. The grade 11 site even has some games posted (no, they're not order of operation or multiplication games).
It's kind of neat to see how other people blog about math and you can get a sneak peak at what you are going to learn in the next few years.
Enjoy the games...I hope you can pull yourself away in time for class on Monday.
Ms. Armstrong

(subtracting polynomials)...Aliens... HEAR MY WISDOM!!

Earthlings: Subtracting polynomials is the same as Adding polynomials except we have to change the subtraction sign into an addition sign.
Aliens: How do you solve this "Wise One"?...... (5x + 10y + 11) - (10x + 15y + 13)
Earthlings: Like this..

Step one:
Write terms in column form with their like terms

(+5x +10y +11)
- ( +10x +15y +13)
_____________________


Step two:
Change the second set of polynomials to the opposite sign and change the subtraction sign to an addition sign, this is called the additive inverse.

(+5x +10y +11)
+ (-10x -15y -13 )
_____________________


Step three:
Add all the like terms together.

(+5x +10y +11)
+ (-10x -15y -13 )
_____________________
-5x -5y -2




Aliens: thank you kind earthling.... maybe now we'll jus bother ms. armstrong more..... for we crave this..... wisdom....



message from me: any questions?? leave a comment!!

The Aliens Have Landed

Hello Jellybeans,

Just this morning, little creatures landed in my back yard demanding to know everything I know about polynomials. Well...you can only imagine my fear. I froze. I couldn't say a word...but, I motioned for them to follow me. This is where you come in.

Each group of aliens has been assigned to learn one piece of the polynomial puzzle and bring it back to their planet. Some will learn about vocabulary, others will learn about adding, others about subtracting, and another group about multiplying. I need all of the 'Flamingo Souffles' and 'Octopus Brownies' to help out. Tell them everything you know.

Now it is your responsibility to pass this information on to another species. If someone posts information that is incorrect, it is your civic duty to leave a comment on the post to correct or clarify the information.

Have fun teaching the universe and beyond !!

Access to Millions of Brains

Hey Jellybeans,
Just like most of you, I'm new to blogging. I'm a little bit uneasy about this new technology...will I say something stupid... will it be a flop...BUT, I'm also excited by the idea that we have access to millions of brains from all around the world. People that we could never meet in our lifetime, that have similar interests and questions are right at our fingertips.
The other day I was marking the mathematical translation puzzles that you were creating and I came across several papers that made me think 'how do you translate that???'.
So... I did what I always do when I'm not sure about a math answer...I marked you wrong (just kidding :) I asked Mr. Kuropatwa. (Remember him, he's the man who lives across the hall). Anyways...he explained that somethings don't translate easily, just like any language there are some things that are difficult to express. Then he said "Why don't you blog about it??"
So, here it goes. Maybe somebody out there...more knowledgable than you or me...has the age old answer to the question...How do they get the caramel inside a Caramilk bar??? Oops, wrong question. How do you translate a mathematical expression that involves more than 1 set of brackets and various orders of operations?
For example: 3x (2x – 6 / 3) + (2x +1)^2
Note to jellybeans: ^ this symbol tells people that the 2 is an exponent because this program does not have that formatting feature.
My translation would be something like this: The sum of all of the difference of two times a number and six divided by three multiplied by three times a number added to all of two times a number and one to the exponent of three.
Problem: how do I show that I've closed the bracket so it doesn't sound like 3 is multiplied by 3x and the exponent is for the whole bracket not just the 1? Aaaaaarggghhh.
Good job on making those puzzles jellybeans, you've really made me think!!
Ms. Armstrong

Check out your new help center

Hello Jellybeans. I hope that everyone had a fabulous day out in the workforce and left a positive impression with future employers. I'm sure that you represented DMCI extremely well and your parents, aunts, uncles, neighbors and friends were proud to have you along side of them today.

While you were away...seeing the world...appreciating the work that others do, I was here at school setting up a blog for you to communicate with your classmates about MATH. This will be the newest place for you to get help with homework and catch up on classes that you have missed. You can write about the topics covered in class, you can post a math question that you are struggling with, or you can respond to someone else's question when you think that you can help them out. The more you post, the more valuable this tool will be towards learning and gaining credit in this class. So have fun... and help one another.

I have started you off by posting some websites that I think you will benefit from. Some are for multiplication practice, others are for integer operations, and others are for order of operations. Check out the sites that you think will help strengthen your skills. After all...you know yourself best.

Here is your assignment:

1. Leave a comment describing where you went for your work placement and how you enjoyed your day. (make sure you use your first name and last initial only - for safety, DO NOT type your whole last name)
2. Click on the link that says email Ms. Armstrong and send me a short email. This way I will have your email address and I can set up your account so you can post messages on the site.
3. Check out any 3 of the links that might help you out.

See you on Monday,
Ms. Armstrong
