Unit 3, Lesson 5
Equivalent Multiplication Expressions
Grade 4
Preparation
Lesson Purpose
The purpose of this lesson is for students to write equivalent expressions for the multiplication of a whole number and a unit fraction, and explain the equivalence.
Lesson Narrative
In previous lessons, students multiplied unit and non-unit fractions by a whole number and represented their reasoning with diagrams and expressions.
In this lesson, students apply these understandings to explain how two multiplication expressions are equivalent. Students use what they know about multiple groups of unit fractions to explain how two different expressions result in the same product (MP7). (Students are not expected to use the term “equivalent expressions.”)

- Generate multiplication expressions that represent a given fraction.
- Justify (using words or other representations) that multiplication expressions involving whole numbers and fractions are equivalent.
- Let's write multiplication expressions in different ways.
