Centimeter Addition Measurement Worksheet

Kids often understand addition before they remember to write the unit. This printable gives them four centimeter addition problems with picture models that show the saved quantities. The pictures support the math, but they are not life-size measuring tools, so the job is to read the given cm amounts and add them.

This page is a good fit when a first grader can count on, write basic addition answers, and recognize that cm means centimeters. If the unit label is the sticky part, point to it before each problem and have your child say “centimeters” out loud. That small pause helps the answer stay tied to the measurement.

The practice works best as shared table time. Ask, “What two measurements are being added?” then let your child write the total. If they rush, cover the next problem with a blank sheet of paper and focus on one line at a time. Before moving on, have them check the number and the unit label together.

When this feels comfortable, keep measurement fresh by changing the kind of unit. A milliliter comparison worksheet gives practice reading and comparing amounts instead of adding centimeters. For one more short follow-up, another milliliter comparison page keeps the same measurement mindset while giving your child a new set of comparisons.
