Unit 4, Lesson 14

Multiply unit fractions by non-unit fractions.

EngageNY 60 min(s)

In this lesson, students continue to understand fraction by fraction multiplication by multiplying unit fractions by non-unit fractions. Students continue to use rectangular fraction models. For example, they will determine the fraction of a pan of crispy rice treats sent to school if Jan has 1/3 of a pan of treats and sends 1/2 of the treats to school. Then they make a connection between the resulting fraction and the original fraction. They notice that the numerator is always the product of the numerators of the factors and that the denominator is the always the product of the denominators of the factors.
