What Is the Result When You Multiply Or Divide a Number by a Fractions
Content Area: Math
Unit Title: Multiply and Divide Fractions Unit: 2
Target Course/Grade Level: Sixth Grade Timeline: 3 weeks
Unit Summary: When describing real-world quantities, fractions are important because many quantities cannot be described using whole numbers. In this chapter, students learn how to multiply and divide fractions. The emphasis is on understanding the concepts and procedures used to perform the operations. Students first use models to find products and quotients. This method allows students to understand how numerators and denominators are related to the operations of multiplication and division. Then students learn and apply the multiplication and division algorithms. By moving from the concrete to the abstract, students will become proficient in multiplying and dividing fractions.

Teacher Notes:
When multiplying a whole number or a mixed number by a proper fraction the product gets smaller and when you are dividing a whole number or a mixed number by a proper fraction the quotient gets smaller.
