Chapter 9 - Multiply Fractions and Whole Numbers
In this chapter, your student is learning how to multiply whole numbers and fractions. The lessons build upon prior knowledge your student has about unit fractions and mixed numbers, as well as the Distributive and the Associative Properties. Area models will help your student visualize multiplication with fractions.
Your student can practice multiplying whole numbers, fractions, and mixed numbers when you are working on a household project, such as installing carpet or cooking with a recipe.
By the end of this chapter, your student should feel confident with the learning targets and success criteria. Encourage your student to think of other contexts in which multiplying whole numbers and fractions is used.
Have a great time completing household projects and cooking!
