5th Grade Fraction Addition & Subtraction Worksheets

Fifth graders must add and subtract fractions with unlike denominators, including mixed numbers, using equivalent fractions to create common denominators (CCSS 5.NF.A.1). This extends fourth-grade work with like denominators and simple unlike-denominator pairs to include cases where neither denominator is a multiple of the other (for example, thirds plus fourths requires twelfths as the common denominator). Students also subtract a fraction from a whole number by rewriting the whole number as a mixed number (5 minus 3/4 becomes 4 and 4/4 minus 3/4). When subtracting mixed numbers, regrouping the whole-number part is the procedural step most students find difficult. Worksheets that separate each skill level (like denominators, related denominators, then unrelated denominators) allow targeted practice before combining types. Problems that ask students to estimate first (the answer should be close to 3) build the number sense needed to catch computation errors.
