4th - 5th Grade

Mathematics

How to Add Fractions with LIKE Denominators is a Grade 4–5 mathematics worksheet focused on adding fractions that have the same denominator. Students complete five fill-in-the-blank problems, including examples with denominators of 5, 15, 24, 11, and 50. Each item requires them to add the numerators while keeping the common denominator unchanged, including sums such as 22/15 and 22/11. This free printable worksheet gives students focused practice with a single fraction-addition procedure before they work with more complex fraction operations. It can support guided instruction, independent practice, or a quick check of whether students understand why like denominators do not need to be added or changed. An answer key is included so teachers can review responses efficiently and identify errors in students’ use of the numerator and denominator.

FAQs

What does this worksheet teach about adding fractions with like denominators?

This Grade 4–5 worksheet teaches students to add the numerators while keeping the common denominator unchanged. Its five fill-in-the-blank problems use like denominators such as 5, 15, 24, 11, and 50, helping students apply the same procedure across fractions with different values.

How can I use this worksheet to teach adding fractions with like denominators?

Model one of the fill-in-the-blank problems by identifying the shared denominator first, then adding only the numerators and recording the resulting fraction. Have students explain why the denominator stays the same before completing the remaining items, including the problems that produce results such as 22/15 and 22/11.

What mistakes should I watch for on this like-denominator fraction worksheet?

Watch for students adding the denominators, changing the denominator, or writing only the sum of the numerators. Students may also treat the repeated 11ths problem differently from the other items, so check that they apply the same rule: add the numerators and retain the common denominator.

How do I assign and grade this fractions worksheet?

You can assign this worksheet as a printable PDF or as a digital quiz on Wayground, and it includes a complete answer key for all five fill-in-the-blank problems. For printable submissions, scan student work with the Wayground for Teachers app to help grade responses efficiently.

How can I differentiate this worksheet for students who need support with fraction addition?

Use the worksheet’s Advanced Settings to adjust font spacing or font size so the fraction expressions and fill-in blanks are easier to read and complete. You can also apply a dyslexia-friendly font or translate the like-denominator fraction problems into another language when appropriate.
