Lesson 2

Hagan su propia recta numérica

Lesson Purpose

The purpose of this lesson is for students to create their own number line to represent and compare fractions.

Lesson Narrative

In previous lessons, students learned to represent fractions on number lines and to record the results of comparisons of fractions with the symbols \(>\), \(=\), or \(<\). In this lesson, students create their own number lines to practice writing fraction comparison statements.

If students need additional support with the concepts in this lesson, refer back to Unit 5, Section B in the curriculum materials.
