Exploring Multiplication and Division Fact Families

The video tutorial explains the relationship between multiplication and division using a fact family triangle. It introduces the concept of a fact family triangle with three numbers, demonstrating multiplication turn around facts with examples like 2 times 10 equals 20 and 10 times 2 equals 20. The tutorial then transitions to creating division facts from these multiplication facts, showing that 20 divided by 2 equals 10 and 20 divided by 10 equals 2.

What is the purpose of using a fact family triangle in mathematics?

• To solve complex equations

• To illustrate the relationship between multiplication and division

• To graph functions
