Lesson 14
¿Cómo comparas fracciones?
Lesson Purpose
The purpose of this lesson is for students to represent and compare fractions in a way that makes sense to them.
Lesson Narrative
Previously, students used various representations to make sense of fractions and their size. In this lesson, students consider representations that will be helpful for comparisons, such as diagrams, fraction strips, and number lines. They also learn that comparisons are valid only when the fractions being compared refer to the same size whole. This lesson does not discuss specific strategies for comparing different types of fractions as the intent is to elicit different ways to reason about comparison.
