Lesson objective: Fluently compute and interpret the quotient and remainder in a fraction division siutation.

This lesson helps to build fluency with computing and interpreting the quotient in a fraction division situation. An area model is used here because it supports the representation of why same size pieces make sense when dividing fractions. This work develops students' understanding that measurement division may be done with common denominators and the result names the number of groups.

Students engage in Mathematical Practice 3 (construct and critique arguments) as they interpet and compute quotients of fractions and make sense of the remainder in fraction division situations.

Key vocabulary:

• common denominator
• dividend
• divisor
• quotient
• remainder
