Lesson 16

Compare Fractions with the Same Numerator

Lesson Purpose

The purpose of this lesson is for students to compare two fractions with the same numerator.

Lesson Narrative

In this lesson, students reason that fractions with the same numerator have the same number of parts, and that the denominator shows the size or length of those parts. Students recognize that as the denominator increases, each part gets smaller. It is important that students develop this understanding rather than learning a rule about comparing fractions with the same numerator.
