## Fraction Multiplication

#### Activity Overview

This activity uses interactive unit squares to explore the concept of fraction multiplication. The concept of fraction multiplication is developed by considering the area of a unit square that has been partitioned into rectangles.

This TI-Nspire™ lesson uses interactive unit squares to explore the concept of fraction multiplication. The concept of fraction multiplication is developed by considering the area of a unit square that has been partitioned into rectangles with dimensions by .  Building on earlier work of finding the area of a rectangle by multiplying side lengths, students investigate the fraction of an area shaded in a unit square. This leads to the generalization that the product of two fractions is the product of the numerators and the product of the denominators.
