Unit 4, Lesson 25

Divide a whole number by a unit fraction.

EngageNY 60 min(s)

In this lesson, students begin understanding division of fractions by dividing a whole number by a unit fraction. They use paper and scissors to model dividing a whole number into fractional groups. For example, finding the number of bags made when Jenny buys 2 pounds of pecans, knowing that she puts 1/2 pound in each bag can be represented by the expression 2 ÷ 1/2. Then students use tape diagrams and number lines to understand division of whole numbers by unit fractions.
