Dividing a Whole Number by a Fraction

Activity Overview

This activity uses unit squares to illustrate the division of a whole number by a unit fraction.

About the Lesson

This TI-Nspire™ lesson uses unit squares to illustrate the division of a whole number, c, by a unit fraction bc-ax-1-b. Once this concept has been established, students build on this thinking to analyze representations of dividing the whole number, c, by the fraction bc-ax-a-b. The activity also allows students to approach the task by considering the relationship between multiplication and division and identifying a missing factor.

Students should have experience with the concepts in the activities Unit Squares and Fractions and Mixed Numbers.

This is Lesson 12 out of 15 in the Building Concepts in Mathematics: Fractions Series.
