Lesson 2: Equivalent Fractions: Number Lines

In this Grade 4 lesson from enVision Mathematics, students learn how to identify and name equivalent fractions by locating the same point on number lines divided into different equal parts, such as showing that 3/4, 6/8, and 9/12 all represent the same distance. Students use number lines as a tool to understand why fractions with different numerators and denominators can be equal, including fractions greater than or equal to 1. The lesson is part of Chapter 8, which extends students' understanding of fraction equivalence and ordering.

Section 1

Identifying Equivalent Fractions on a Number Line

Property

If two fractions ab\frac{a}{b} and cd\frac{c}{d} represent the same point on a number line, then they are equivalent: ab=cd\frac{a}{b} = \frac{c}{d}.
