Centimeter Measurement Subtraction Worksheet

The printable measurement worksheet gives first graders four subtraction problems written in centimeters. Children read the saved quantities, look at the illustrated rulers, scales, or measuring containers, and practice finding the difference in cm.

At seven, children often understand subtraction facts but stall when centimeters join the problem. Unit comparison matters now because first graders are moving from counting objects to reading and comparing measurements on paper.

Sit beside your child with a pencil and ask your child to circle the two measurements in each problem before subtracting. After your child writes an answer, have your child say the full sentence, such as “12 cm minus 5 cm equals 7 cm,” so the unit stays attached to the number.

The illustrated rulers, scales, or measuring containers match the saved quantities, so the page gives a concrete hint without turning into a guessing game. The pictures are models, not life-size measuring tools, which keeps the focus on centimeter subtraction, unit labels, and comparison thinking.
