After distributing the following problems what two equations would you have and what would the product be?
16 x 4 =
(10 + 6) X 4 =
10 x 4 = 40
6 x 4 = 24
24 + 40 = 64
16 x 4 = 64

What is the Associative Property?
The Associative property is when we take a 3 factor multiplication problem and group them two different ways to show the answer is the same: For example
(3 X 4) X 2 = 24 or 3 X (4 X 2) = 24
12 X 2 = 24 3 X 12 = 24
