Lesson 17
Compare Fractions
Lesson Purpose
The purpose of this lesson is for students to compare two fractions with the same numerator or the same denominator in and out of context and to justify their conclusions.
Lesson Narrative
In previous lessons, students learned what it means for fractions to be equivalent, and compared two fractions with the same denominator or the same numerator. In this lesson, students apply their knowledge to compare fractions in and out of context and have an opportunity to generalize about what they have learned about fraction comparison.
