Centimeter Measurement Addition Worksheet

Kids often stall when a math problem has both numbers and units. This printable keeps the work focused: read each saved centimeter quantity, add the two measurements, and write the total in cm. There are four addition problems on the page, with illustrated rulers, scales, or measuring containers that match the given quantities.

This page fits a first grader who is ready to add small measurements and say the unit out loud. The pictures are models, not life-size measuring tools, so use them as visual clues instead of asking your child to measure the paper. If the centimeter label gets skipped, point to it and ask, “What unit should go after the answer?”

The practice works best when you slow the first problem down together. Have your child read both measurements, add the numbers, then write the sum with cm. After all four are done, invite a quick check by looking across the answers and naming which total is longer or shorter. For a related next page, centimeter measurement subtraction practice helps children use the same unit while taking away instead of adding.

If attention is fading, fold the page so only one or two problems show at a time. A short, calm round is enough. When your child is comfortable adding centimeters, you can connect the idea to another unit with the feet comparison measurement worksheet, which keeps the focus on reading units and comparing measurements without needing real tools.
