Exploring Fact Families in Multiplication and Division

The video tutorial introduces the concept of fact families in multiplication and division, explaining how they consist of related equations using the same numbers. It provides examples, such as using the numbers 8, 5, and 40, to illustrate how knowing one equation can help solve others. The tutorial also introduces a visual method of organizing fact families into a 'house' model, with the largest number at the top. Viewers are encouraged to practice creating their own fact families and are given a preview of the next video, which will offer a trick for multiplication facts.

What is a fact family in the context of multiplication and division?
