About this worksheet

What students practice

Students rewrite subtraction of rational numbers as addition of the opposite.
Students calculate distances between rational numbers using absolute differences.
Students distinguish signed differences from nonnegative gaps in track meet results.

How to use

Have students show a rewritten addition expression beside each subtraction. Discuss when the results board needs a signed difference and when it needs a nonnegative gap.

Curriculum

Common Core standard covered
