Lesson Plan: Subtracting Fractions with Like Denominators

In this fourth lesson of the Adding and Subtracting Fractions Unit, students will learn how to subtract fractions with like denominators. Since the denominators are the same, students can focus on subtracting numerators and reinforcing their understanding of fraction subtraction.

Students will:

• Understand why fractions with the same denominator can be subtracted directly
• Use fraction bars and number lines to visualize fraction subtraction
• Practice subtracting fractions and simplifying answers when necessary
• Apply their understanding to solve real-world fraction problems

Designed for grades 3-5, this lesson aligns with Common Core standards and builds on students’ prior knowledge of fraction concepts. Through guided practice and engaging activities, students will develop fluency in subtracting fractions with like denominators.

This is the fourth lesson in a ten-part unit on adding and subtracting fractions. Future lessons will introduce subtracting fractions with unlike denominators, working with mixed numbers, and solving fraction word problems.
