Adding and Subtracting Fractions With Like Denominators

Adding and subtracting fractions with like denominators is a key upper-elementary math skill. When the denominators match, students can focus on understanding how numerators combine or separate — without the added challenge of finding common denominators.

This free printable worksheet gives students clear, structured practice with both fraction addition and subtraction using like denominators.

What Students Practice

  • Adding fractions with the same denominator

  • Subtracting fractions with the same denominator

  • Identifying whether to add or subtract based on the symbol

  • Writing simplified fraction answers

The problems are numbers-only, making this worksheet ideal once students have moved beyond visual models and are ready to build procedural confidence.

How to Use This Worksheet

  • Whole-group or small-group math instruction

  • Independent practice or homework

  • Math centers or early finisher work

  • Review before quizzes or assessments

This worksheet works well for 3rd and 4th grade math, intervention groups, or extra reinforcement at home.

Why Like Denominators Matter

When fractions share the same denominator, students learn that:

  • The size of the pieces stays the same

  • Only the number of pieces changes

  • The denominator remains unchanged

This foundational understanding supports future skills like working with unlike denominators and mixed numbers.
