Module 8: Multiplying FractionsMath 5B  Course Guide
Module Overview:
In this module, students will learn about multiplying whole numbers, mixed numbers, and fractions, and solving and creating their own word problems. They will learn about how to apply the commutative property to mixed products, finding the area of a shape with fractional sides, finding area using multiplication, and learn how to find the perimeter. Students will define the identity property of multiplication, apply the identity of multiplication to fractions, recognize that multiplying a whole number by a fraction less than 1 results in a product smaller than that whole number, and recognize that multiplying a whole number by a fraction greater than 1 results in a product greater than that whole number. Finally, students will Identify the solution sets of inequalities, graph the solution sets of inequalities on a number line, and compare the products of two multiplication sentences to determine which is greater.

Module Suggested Read Aloud Books:
Take time to read to your student or have them read aloud to you. Read a different book each day. While reading the book point out concepts being taught. You may purchase these books or find them at your local library. Suggested things to discuss while reading the book:
 What is the main idea?
 What are three things new you learned?
 How does this book relate to what you are learning about?
