This Problem Set is a part of the Lesson 26, Unit 5, Grade 3. In this lesson, students continue showing the equivalence of fractions and whole numbers using number lines. Using number bonds, they discuss the equivalence of 2/2, 4/4, and 1 whole. Then they use number bonds and the number line to represent the equivalence of 0/4 and 0, the equivalence of 4/4 and 1, and the equivalence of 8/4 and 2.
