Section 1
Writing Expressions from Area Models
Property
An area model divided into horizontal parts (rows) and vertical parts (columns) represents the multiplication of two unit fractions, . The product is .
In this Grade 5 Illustrative Mathematics lesson from Chapter 3: Multiplying and Dividing Fractions, students learn to multiply unit fractions by applying the concept that multiplying by a unit fraction is the same as finding a fractional part of a quantity. Students use visual models and equations to develop fluency with expressions such as 1/2 × 1/3, building foundational understanding of fraction multiplication.
