Hi today I'm going to show you how to solve 3 algebra equations. I'll be teaching you a 2 step multiplying equation, 2 step dividing equation, and a distributive equation.

Definitions

Constant -  A quantity that does not change its value.

Coefficient -  A number multiplied by a variable in an algebraic expression.
Variable - A letter or symbol used to represent a number.
Distributive Property - The sum of two addends multiplied by a number is the sum of the product of each addend and the number. 

2 step multiplying equations 

6r + 6 = 18

First you isolate the variable, by isolating it you make a zero pair for your constant, then you do it on the other side because you did it there.

6r + 6 - 6 = 18 - 6

6r = 12 

Then you balance it by dividing both sides by the coefficient then you fully have your variable isolated 

6r = 12

6       6

r = 2

Now we verify it, first you rewrite your equation 

6r + 6 = 18

Now substitute your variable with 3 

6(2) + 6 = 18

Now you multiply your coefficient by 2

12 + 6 = 18 

Now you verify it by adding your coefficient and your constant

18 = 18

And now you got your answer, here a link to learn more about 2 step multiplying equations

2 step dividing equations

m + 2 = 18

3

First you want to isolate the variable by making a zero pair for your constant then you do the same thing on the other side 

m + 2 - 2 = 18 - 2

3

m = 16

3

Then you it by multiplying your variable and you do the same thing on the other side 

(3)m = 16(3)

     3

m = 48

Now you verify it, first you rewrite your equation

m + 2 = 18

3

Now substitute your variable with 48 

48 + 2 = 18

3

The you divide your coefficient  

16 + 2 = 18

Then you verify it by adding the coefficient with the constant

18 = 18

Now your done, here a link to learn more about 2 step dividing equations

Distributive Property

Now I will teach you about distributive equations 

4 (m - 3) = 12 

First you multiply the constant and the variable by the coefficient.
4 (m - 3) = 12
    m - 3
    m - 3
    m - 3
    m - 3

You would get
4m - 12 = 12
Then solve it like a 2 step multiply equation
4m - 12 + 12 = 12 + 12
4m = 24
4m = 24
4         4
m = 6
4m - 12 = 12 
4(6) - 12 = 12
24 - 12 = 12
12 = 12 
Now I will do in a diagram

   

  

4 (m - 3) = 12
Now you do the same steps as you would do on the 2 step multiply equation.
4 (6 - 3) = 12
4 (3) = 12
12 = 12
Now your done here's a link to learn more about Distributive Property

This the end of my post I hope you learned something.

Anthony's Integer Scribe Post

Today in class we learned to model multiplying integers and how to write them out. There's different types to multiple with integers, like this (+) x (+) =, (+) x (-) =, (-) x (+) =, (-) x (-) =.

Here are some examples:

Anthony's Pay it Forward

Part 1 
What is pay it forward?
I think Pay it forward is when you do good deeds to people and receive nothing back. Then those people do a good deed to other people.

In the movie Pay it Forward a boy name Trevor that's in grade 7 started this movement. Trevor created this for his grade 7 project. It was a big success and random acts of kindness have been given all over the U.S.

Part 2
What was your Pay it  Forward act of kindness? 
My act of kindness was donating gifts to the Children's Hospital.
Why did you choose this activity? 
I chose this act of kindness because the children in the hospital may have to stay there during the holidays and in a way the gifts I gave them may make them feel better and put a smile on their face.    
Who did you help?
I helped the kids in the Children's Hospital. 
What did you do?
I made gift bags for the children in the Children's Hospital.  
When did you do you act of kindness?
December 4th, 2012 

Part 3
How did your act of kindness go?

My act of kindness went really well.

What Happened?
I gave the gift bags to Tania the lady who would distribute them to the kids. I wasn't allowed to give it to them myself due to privacy reasons.

How did you feel?

I felt happy that I helped kids form the hospital. 

How did the person or people react?
Tania was very nice and thought that it was very nice of me to do that for the children.

Did you ask the person or people to "Pay It Forward"?
Yes, I asked them to Pay it Forward.

How did they react to your request?
They said they will Pay it Forward.

Part 4

Why is the idea of "Pay it Forward" important?

The idea of "Pay it Forward" is important because the small things you do for people can make a big difference in the world by paying it forward. 

Has your act of kindness made a difference?

I think my act of kindness made a difference.

Anthony's Fraction Test Corrections

In computer terminology, a bit is 1/8 of
a byte. How many bits equal 16 bytes?

Tamar had 1/2 of an apple pie in her
refrigerator. She ate 1/4 of this piece
of pie. What fraction of a whole pie 
did she eat?

1/4 / 1/3

In class today we learned to divide fraction's, how to model them, put them on  a number line and how to rewrite them in 3 ways

3 ways to rewrite a fraction:

How Divide Fractions:

You can solve dividing fractions statements in 3 ways 

The first way you can solve 6 divide 1/2 is to make a number line. The interval in this number is 1/2, so you make 12 bumps to get to 6, The answer is 12. 

The second way you can solve it by is by 
making 1/2 a whole, you can make it
a whole by multiplying it by a reciprocal 
which gives you 1. Then take that fraction 
and multiple with the other fraction.






The third way of solving it is to make a model,
make 6 squares then you split it in to half, then 
you count the rectangles and the answer is 12






How to solve 1/2 divide by 2:


  You share 1/2 between 2. You have
  1/2 so you half the half then you share 
   it and you get 1/4.
