# 5th Grade Common Core: 5.NF.1

Common Core Identifier: 5.NF.1 / Grade: 5

Curriculum: Number And Operations - Fractions: Use Equivalent Fractions As A Strategy To Add And Subtract Fractions.

Detail: 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.)

47 Common Core State Standards (CCSS) aligned worksheets found:
Another worksheet for adding fractions with denominators that are different. (example: 1/4 + 1/2 = 3/4) Vertical problems.
