Exploring the Distributive Property of Multiplication

The video tutorial explains the distributive property of multiplication, also known as the break apart strategy. It uses arrays to demonstrate how large numbers can be broken into smaller, more manageable parts for easier multiplication. Several examples are provided, including arrays of 5x7, 3x9, 6x8, and 4x7, to illustrate the concept. The tutorial emphasizes that the method of breaking apart numbers can vary, but the final result remains consistent. The video concludes with a reminder to practice using the attached worksheet.
