4th - 4th Grade
Mathematics
This Grade 4 mathematics worksheet gives students focused practice adding fractions with like denominators and simplifying the results. Across 14 problems—1 multiple-choice item, 8 multiple-select items, and 5 fill-in-the-blank items—students add the numerators, keep the common denominator, and identify or write an equivalent fraction in simplest form. Several multiple-select questions require students to recognize equivalent representations, such as 3/6 and 1/2 or 10/12 and 5/6, rather than choosing only one notation. Use this worksheet for independent practice, guided review, homework, or a quick check of fraction-addition fluency in Grade 4 math. Students must show that they can calculate sums such as 7/8, 11/12, and 4/5 and apply simplification consistently across different response types. It is a free printable worksheet with a complete answer key for efficient checking and feedback.

This Grade 4 worksheet covers adding fractions with like denominators and simplifying the sums to equivalent fractions in simplest form. Its 14 items use multiple choice, multiple select, and fill-in-the-blank formats, requiring students to calculate sums and, in several items, recognize equivalent answers such as 4/8 and 1/2.
Model one item by adding the numerators while keeping the denominator, then simplify the result when possible. Next, use the multiple-select questions to discuss why equivalent forms such as 3/6 and 1/2 can both represent the correct sum before assigning the fill-in-the-blank items for independent practice.
Watch for students adding the denominators, changing the denominator unnecessarily, or stopping before simplifying a result such as 10/12 to 5/6. In the multiple-select items, students may choose only one correct representation even when both an unsimplified fraction and its equivalent simplified form are listed.
You can assign this adding-fractions worksheet as a printable PDF or as a digital quiz on Wayground. It includes a complete answer key, and printable submissions can be graded by scanning student work with the Wayground for Teachers app.
For the fraction sums and answer choices on this worksheet, use Advanced Settings to adjust font spacing from normal to medium or wide and change the font size from S through XL. You can also enable a dyslexia-friendly font or translate the worksheet into another language when those options better support access to the multiple-choice, multiple-select, and fill-in-the-blank items.
