Add / Subtract Unlike Denominators Color by Number rewards every correct answer with another piece of a hidden picture. Students solve each problem, match the answer to the color key, and a hidden picture appears region by region. Students find common denominators to add and subtract fractions. Built for Grade 5 and aligned to 5.NF.A.1. It's no-prep and self-checking, perfect for centers, fast finishers, review days, or sub plans, with both a print-ready PDF and an interactive answer-key version in every download.
Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)
