scribe - tiinaa

today in class we continued working on the piece of paper with 12 squares. in the 4th square under transposing, we wrote:

4(2x + 2) = 5(x + 7)
8x + 8 = 5x + 35
-5x - 8 = -5x - 8
3x/3 = 27/3

x = 9

in the 5th box under transposing, we wrote:

-there is a variable on both sides of the = sign
-use the distributive property to get rid of the brackets
-variables go left
-integers go right
-solve 1 step equation

then after that, we had to work on page 41 in the "sammy the seal" booklet.

scribe - annabelle

today in class we folded a piece of paper into 12 squares. On the first square we wrote collecting like terms. Then we opened it and we wrote in the 1st row in the 1st square:

3x-3+6x+9=24
3x+6x-3+9=24
9x+6=24-6
9 -6 9

x= 13/9 =2

we wrote:
- choose 1 of 2 terms
- circle them
- add like terms
- solve the equation when you have only 1 of each term

we did another example:

-2x-3x+3+2=10
-5x+5=10 -5
/-5 -5

we wrote:
- circle the first term
- find like terms
- put the like terms together
*cancel using integer rules

we went onto something new, transposing:
6x+5=2x+13
-2x -5 = -2x -5
When you simplify it becomes
4x/4 = 8/4 x=2

6(2)+5=2(2)+13
17 = 17

we wrote:
- you need the variable (letter) on the left and numbers on the right
- cancel the right variable with its opposite
- cancel right integer with its opposite

then we had to work on the 'sammy the seal' booklet and finish page 40

Scribe Post.

Today in class we corrected the homework we had yesterday, not a lot volunteered to go up and answer them though.
Then we took down notes on
The Distributive Property.



This is pretty simple and easy to understand.

Uhh then we have page 41 in that booklet for homework.

That's all : ). I think?

what does z equal?

Heres a question for anyone in 8-73. Show your work too. Post your answer in the the comments. Use the following information given to figure out the value for z. The equation isn't spaced, so you can use your head more. The question is also different from the ones taught in math class.

a=2
n=3

86n-21n-15a+13+34a-13+26-51z=208

Steephaanieee's Scribee<3

This is what we did today in math. We reviewed Like Terms. We also learned that we put the terms in their own "bags"

e.g1

2p+7p
two pears plus seven pineapples equals...9 pears ( both pears, same bag)
=9p

e.g2

3m+n+4n-m

three mango's plus a nectarine plus four nectarines subtract a mango

Serperate the different fruits
3m-1m= 2m

4n+1n= 5n

there for

2m+5n

scriiibe (: [ Feb. 20/ 06 ]


the first thing we did in class was take down what we should have in our math section for our electronic portfolios.



then we took notes on collecting like terms.

- Terms that have the same variable parts are called like terms.

E.G1 ;; 3x + 7 = 40
Add 10x/ 10 ... 40/ 10
x = 4
3(4) + 7(4) = 40

E.G2 ;; 4x + 6 - 2x -9 = 9
4x - 2x + 6 - 9 = 9
2x - 3 = 9 + 3/ 2
x = 12/ 2
x = 6


You want 1 variable and 1 integer term on each side. After you have simplified
3x2 + 2x - x = 5x
3x2 - x2 + 2x +5x
2x2 +7x

aaand... we have pages 6.6 / 6.7 [ 1-18 ]
and 6.8 [ 1-20 ]

Scribe 6

1. Today we learned about multiplying and dividing equations.

E.G:
x2=10
x=10/2
x=5

E.G.2:
x/8=3
x=8(3)
x=24

2. the notes for today were:
1)isolate the variable
2)cancel using the opposite
3)Balance
4)substitute to check
*show division as a bracket
*when when you cancel on multiplication if you still have 1x

3. do page 6.4 Solving Equations by Division
6.5 Solving Equations by Multiplication

Lost Algebra

I created a post on the weekend all about the algebra you are doing. I am reposting it for your amusement. Please complete as much of this as you can and leave a comment behind about how you did.

Remember me Grade 8’s. Since I have been gone …only two days you must be missing me. Even if you are not missing me here are some excellent links to reinforce your learning.

The foundation to understanding algebra is to know integers. Here are two links that will reinforce what you need to know.

Try this Integer Quiz. If this is not familiar to you remember your order of operations and try again.

From this link you can see a movie on adding and subtracting integers. It is well done. If this link does not bring up the movie immediately click on the adding and subtracting integer link on the page.


Your first algebra lessons are dealing with words like term, variable, expression and equations.


Here are some helpful resources for you.
Extra help words to expressions
Extra help on variables and expressions

Here are three quizzes to see how well you did.

Substitution algebra
Solving Equations using Addition or Subtraction
Solving Equations using Division or Multiplication

Remember Leave comments to tell me how you did.

Scribes???

Being a class scribe is a serious responsibility. You need to recapture the class for that day and post it for all to see.

As Richard has said in his posts

” The purpose of a scribe is to inform the reader what your doing and by doing so you relearn what you learned that day making you just a bit more smarter. Also if the reader reads the scribe then they also relearn. To think about it. Scribing is all about learning and learning… etc.”

Try to scribe or comment daily.

Look I'm Back

Sorry I haven’t been commenting or visiting lately. I’ve been crazy studying for exams… But now that Second Semester has started at Daniel Mac. I’m back. Hahaha. Now that I have seen that you guys are scribing. There are some excellent scribes going on and I assure you they will get better. You just have to push around each other on the blog. That’s the evolution of a blogger right there. You guys have to compete with each other to see who’s the best blogger out there. Hahahaha.

There are plenty of Examples of scribing.

Super (Secret) Scribe

Scribe or What

Scribe

Scribe Scribles

Yeah there all from the PC30S blog. Hahaha. Well you see. The purpose of a scribe is to inform the reader what your doing and by doing so you relearn what you learned that day making you just a bit more smarter. Also if the reader reads the scribe then they also relearn. To think about it. Scribing is all about learning and learning… etc.

So keep those scribes coming. And here’s a tip. Like in the examples that I posted. Try to use photos to make your scribe look even more better. Hahaha

Help the scribe

Some advise to bloggers. You need to be prepared to put a post up to the blog. People are counting on you to keep the scribe alive. If you are having difficulty post a blog and then go back in and edit the scribe.

To the scribes fellow classmates, If the scribe needs to have information added to it, post comments and add information you think will be helpful.

You all are doing a great job. I miss being at school. This is my link to you right now. Keep me informed and I will add comments if I can.

Keep scribbling.

Third Scribe

1.Today in class, we learned about multiplying integers combined with subtraction and adding. We also had a quiz out of ten. It was easy.
2.During these activities, we learned the order of operations in a grade 9 math question. We had to box groups with its chaperone too in the questions. The chaperone is the symbol to the left of each group.
Example:
[(-2)(3)] [+ 2(-3)] [- (6)(1)]=
--------- --------- ----------
3.This information to me is new.
4.It was also easy enough to understand.
5.I understand everything and have no questions.
6.The only funny thing that happened in class was Brandon getting 10/10.
7.I don't know if there are any links.
