Big Ideas: Multiplication is the inverse of division and can be used to find answers to division problems. This lesson asks students to find missing parts to a division problem when you are dividing a whole number by a unit fraction. This task encourages students to use the relationship between multiplication and division in order to find the missing parts to the division problems. It should follow strong conceptualized lessons where students worked to construct many models of fraction division. The mathematical concepts in this lesson build toward students' future work with division of fractions in sixth grade. Vocabulary: unit fraction, dividend, divisor, quotient, whole number Special Materials: None
