1. Two Important Math Properties to Know Commutative Property of Multiplication: The order of a Mulitplication Problem doesn’t matter, the product is still the same! 5 x 6 = 6 x 5 Associative Property of Multiplication: Think grouping with parentheses. You can change the grouping of the problem, yet the product is still the same! (5 x 6) x 2 = 5 x (6 x 2)

2. Now Practice: Rewrite this problem using the Commutative Property of Multiplication 5 x 6 x 7 = ____________________ Rewrite this problem using the Associative Property of Multiplication (7 x 8) x 2 = _________________________
