Fraction Sums includes 4 cross-number puzzles. Students add horizontally and vertically to find the sums of fractions. Last students find the sum of the sums both horizontally and vertically.
Puzzles would work well in math stations, as warmups or as homework!
Fraction Sums supports the Common Core standard, CCSS.Math.Content.5.NF.A.1 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.) from Grade 5. The game is appropriate for students who have learned to add fractions with unlike denominators.
