Associative Property

Associative Property

With Multiplication

What is the associative property?

When you have three or more factors, you can group them in different ways to multiply in parts and still get the same product.

Ex: 2 x (3 x 4) = (2 x 3) x 4

2 x 12 = 6 x 4

24 = 24

Multiple Choice

When looking at the associative property we should focus on...

• where the parentheses are

• the order of the factors

• how the factors are grouped

• All of the above

Let's do one together!

4 x (1 x 5) = ___________

4 x (1 x 5) = (4 x 1) x 5

4 x 5 = 4 x 5

Multiple Choice

Which one is the associative property to:

(8 x 2) x 4

• 4 x 2 x 8

• (4 x 2) x 8

• 8 x (2 x 4)

• (8 x 2) x4

Multiple Choice

Which one is the associative property to:

6 x (3 x 2)

• (6 x 2) x 3

• (6 x 3) x 2

• 6 x (2 x 3)

• 6 x (3 x 2)

Look at the factors, group them in a different way, multiply in parts and find the product for: (4 x 2) x 5 = ________

Step 1: (4 x 2) x 5 = 4 x (2 x 5)

Step 2: 8 x 5 = 4 x10

Step 3: 40 = 40
