Checking Division with Fractional Quotients Using Inverse Operations

This lesson teaches how to check division with fractional quotients using the inverse relationship between multiplication and division. It covers the concept of fact families and demonstrates the process through word problems involving licorice ropes and cat food. By using multiplication to verify division results, students learn to ensure their answers are correct.

What are inverse operations and how can they be used to check division?

Explain how fact families relate to division and multiplication.

In the example of dividing 2 licorice ropes among 3 children, how do you determine how much each child gets?

How can you verify that 3 times 2/3 equals 2 using multiplication?

Describe the process of checking the division of 16 pounds of cat food among 5 kittens using multiplication.
