Exploring the Associative Property of Multiplication

The video tutorial covers the associative property of multiplication, explaining that the grouping of numbers does not affect their product. It provides examples of multiplying three numbers using different grouping strategies and demonstrates how to find a missing factor in a multiplication problem. The tutorial concludes with practice problems for students to apply the concepts learned.

What does the associative property of multiplication state?

• The order of numbers does not change their product.

• The sum of numbers remains the same regardless of grouping.

• The difference of numbers remains the same regardless of grouping.

• The way numbers are grouped does not change their product.
