In this Grade 5 Eureka Math lesson from Chapter 23, students learn to multiply unit fractions by non-unit fractions, such as finding 1/3 of 3/5, by drawing rectangular fraction models and writing multiplication sentences. The lesson builds on prior knowledge of unit fraction multiplication to help students understand how multiplying a unit fraction by a non-unit fraction produces a simplified product. Students also practice simplifying results like 3/15 to equivalent fractions such as 1/5.
Section 1
Connecting Area Models to the Multiplication Algorithm
When multiplying a unit fraction by a non-unit fraction, the area model shows that the product can be found by multiplying the numerators to find the number of double-shaded parts and multiplying the denominators to find the total number of parts in the whole.
