Centimeter Measurement Subtraction Worksheet

Measurement subtraction can feel odd at first because kids have to think about the number and the unit at the same time. On this page, they solve four subtraction problems in centimeters, using the illustrated measuring models as the quantities to compare and subtract.

This is a good fit when a first grader can read small whole numbers, recognize cm as centimeters, and understand that subtraction can mean finding what is left or how much less. The pictures are models, not life-size measuring tools, so the goal is to read the shown amounts rather than measure the printed page.

Sit together for the first problem and ask, “What amount do you see first?” Then have them point to the second amount, say the subtraction sentence aloud, and write the difference with the unit. If they stall, cover extra details with a finger and focus on the two shown quantities before doing the subtraction.

After finishing, invite a quick check by reading each answer as “centimeters” after the number and asking if it makes sense. For more comparison with length units, try feet comparison measurement practice. To switch units while keeping number work familiar, use milliliter addition measurement practice next.
