About this worksheet

What students practice

  • Students solve story problems that add and subtract fractions with unlike denominators.
  • Students choose the equation that matches a fraction story problem.
  • Students use benchmark fractions to estimate sums and check if answers make sense.

How to use

Use after students can add and subtract fractions with unlike denominators. Have them estimate each answer with benchmarks before solving, then compare.
