Section 1
Introduction: A Fraction of a Fraction
Property
Finding a fraction of another fraction means you are taking a part of an existing part. For example, taking one-half of a one-half piece results in a one-fourth piece of the original whole.
In this Grade 5 lesson from enVision Mathematics Chapter 8, students learn how to multiply two fractions using area models, grids, and number lines, such as finding that one-third times one-fourth equals one-twelfth by identifying the overlap in a shaded grid. Students explore multiplying fractions with both unit fractions and non-unit fractions, applying the concept that multiplying two fractions produces a product smaller than either factor. Practice problems connect fraction multiplication to real-world contexts and build toward solving equations with unknown factors.

Section 2
Visual Models for Fraction Multiplication
Use rectangular area models to visualize and calculate fraction multiplication.
Divide a rectangle into equal parts to represent each fraction, then find the overlapping region to determine the product.
This visual approach shows that multiplying fractions means finding a fractional part of a fractional part.
