About this worksheet

What students practice

Students solve story problems that add and subtract fractions with unlike denominators.
Students use benchmark fractions such as 1/2 and 1 to judge if an answer is reasonable.
Students solve two-step story problems with mixed numbers and unlike denominators.

How to use

Use after students can find common denominators. Ask them to estimate with 0, 1/2, and 1 before solving, then compare the estimate to the exact answer.
