Math 5 Ch. 3 Lesson 1 Multiplication Properties

by Amanda Maynard

​Commutative Property of Multiplication

​

​Changing the order of the factors

does NOT change the product.

​

Poll

Which is an example of the Commutative Property of Multiplication?

• 6 x 3 = 6 x 3

• 6 x 3 = 3 x 6

• 6 + 3 = 3 + 6

​Associative Property of Multiplication

​

​Changing the grouping of factors does not change the product.

Poll

Which is an example of the Associative Property of Multiplication?

• 2 x (3 x 5) = (2 x 3) x 5

• 2 + (3 + 5) = (2 + 3) + 5

• 2 x (3 x 5) = 5 x (3 x 2)

​Identity Property of Multiplication

​

The product of 1 and a number is the same as that number.

Poll

Which is an example of the Identity Property of Multiplication?

• 13 x 0 = 13

• 13 + 1 = 14

• 13 x 1 = 13

​Zero Property of Multiplication

​

The product of zero and a number is zero.

Poll

Which is an example of the Zero Property of Multiplication?

• 0 x 13 = 13

• 0 x 13 = 0

• 13 x 1 = 13

​Distributive Property of Multiplication

​

​When the same factor is distributed across two addends, the product does not change.

Poll

Which is an example of the Distributive Property of Multiplication?

• 3 x (1 + 6) = (3 + 1) x (3 + 6)

• 3 x (1 + 6) = (3 x 3) + (1 x 6)

• 3 x (1 + 6) = (3 x 1) + (3 x 6)
