Module 12

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

6.EE.A.2 6.EE.A.3 6.EE.A.4

Lesson 12: page 54 example 1

Example 1: pg. 54-55

-(-5)

How would the model look if we grouped together the a’s and then grouped together the b’s?

What expression could we write to represent the new diagram?

What conclusion can we draw from the models about equivalent expressions? 2(a+b) = 2a + 2b

There are 2 a’s and 2 b’s

Example 2: pg. 55

Double is the same as multiplying by two.2(3x+4y) or 6x + 8y

The first expression is in factored form, and the second expression is in expanded form.

We can make a model of 3x + 4y.

Example 2: pg. 56

How can we change the model to show 2(3x+4y)?

We can make two copies of the model.

Are there terms that we can combine in this example?

Yes, there are 6 x’s and 8 y’s. So the model is showing 6x+8y.What is an equivalent expression that we can use to

represent 2(3x+4y)?

2(3x+4) = 6x + 8y, this is the same as 2(3x) +2(4y).

How do you feel?

Example 3 pg. 56

y(4x+5)

y(4x) + y(5)4xy + 5y
