The Distributive Property

We are learning how to simplify expressions using the Distributive Property.

Wednesday, April 19, 2023

Team Investigation…

With your team simplify the given expressions using the Order or Operations.

When you are done draw lines between any expressions that have the same solution.

Last reflect with you team about What similarities do you notice between the expressions that you matched from “Column 1” and “Column 2?”

Do you see any patterns or trends?

The Distributive Property

A(B + C) = _________________

-or-

A(B – C) = _________________

A(B) + A(C)

A(B) – A(C)

Use the Distributive Property to write the expression below in an equivalent form…

7 3 10

6 7 3

8 2 12 8

3 1 4 2 7 10

= ______________________

= ______________________

= ______________________

= __________________________

7(3) + 7(10)

6(7) – 6(3)

8(2) + 8(12) + 8(8)

3(1) - 3(4) + 3(2) – 3(7) + 3(10)

You can even use the distributive property backwards to help find the answer to a difficult multiplication problem.

For example…try to multiply 9(107) by doing…

9(107) = 9(100 + 7)

= 9(100) + 9(7)

= 900 + 63

= 963

You can even use the distributive property backwards to help find the answer to a difficult multiplication problem.

For example…try to multiply 3(46) by doing…

3(46) = 3(50 – 4)

= 3(50) – 3(4)

= 150 – 12

= 138

B. 3(-9 – 1 + 3) = 3(-9) + 3(1) + 3(3)

C. -14(-8 + 7) = -14 + (-8) + 7

D. (-3 – 5 + 2)(-15) = -3(-15) – 5(-15) + 2(-15)
