Unit 3, Lesson 5
Equivalent Multiplication Expressions
Grade 4
Preparation
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.”)
