1. Complete the GCF sprint, you will have 5 minutes:
Find the GCF of each problem (Greatest Common Factor) (Remember: ask yourself, what is the largest number they both share?)

Module 11
SWBAT:
Model and write equivalent expressions using the distributive property. Students will move from an expanded form to a factored form of an expression.

4. ‪Lesson 11: page 47 example 1 2 2
The sum of two groups of five and two groups of three
2 x x 3

5. -(-5) Example 1: pg. 47 2 2 Two groups of the sum of five and three
(5+3) + (5+3) or 2(5+3)

6. Yes, because both expressions have two 5s and two 3s
Yes, because both expressions have two 5s and two 3s. Therefore, 2x5 + 2x3= 2(5+3)
On the left hand side, 2 is being multiplied by 5 and then by 3 before adding the products together. On the other side, the 5 and 3 are added first and then multiplied by 2.
Distributive Property

7. Example 2: pg. 48
a plus a plus b plus b, two a’s plus two b’s, two times a plus two times b.
There are 2 a’s or 2 x a 2 2

8. 2a + 2b 2 2
(a+b) + (a+b)= 2(a+b)
Yes, both have 2 a’s and 2 b’s. 2a+2b=2(a+b)

10. Example 3 pg. 49
3(f+g)
We need to rewrite the expression as an equivalent expression in factored form which means the expression is written as the product of factors. The number outside the parentheses is the GCF
3 * f + 3 * g 3
3 goes on the outside and f + g go inside the parentheses 3(f+g)

11. Example 3 pg. 50 2*3 * x + 3 * 3*y 3 3(2x+3y)
We need to rewrite the expression as an equivalent expression in factored form which means the expression is written as the product of factors. The number outside the parentheses is the GCF
2*3 * x + 3 * 3*y
Factor out the 3 from both terms and put it outside parentheses. What is left in the terms goes inside the parentheses. 3(2x +3y) 3

14. 8(3b+1)
I first expand each term. I know that 8 goes into 24, so I used it in the expansions. 2*2*2*3*b + 2*2*2. I determined that 8 is the common factor, so on the outside I wrote 8 and the inside I wrote the leftover factor 3b+1
When I factor out a number, I am leaving behind the other factor that multiplies to make the original number. In this case when I factor out an 8 from 8, I am left with a 1 because 8*1=8
In the first 2 examples, we saw that we could rewrite the expressions by thinking about groups. We can either think of 24b +8 as 8 groups of 3b and 8 groups of 1 or as 8 groups of the sum of 3b+1. This shows that 8(3b) + 8(1)= 8(3b+1) is the same as 24b +8.
