Centimeter measurement → Add saved cm quantities → Child combines two measurements and records a clear total in centimeters.
Picture models → Connect images to numbers → Child sees rulers, scales, and containers as clues for measurement problems.
Units and comparison → Notice matching centimeter units → Child compares quantities more confidently before choosing an addition strategy.

This printable measurement worksheet gives first graders four addition problems in centimeters. Each problem uses an illustrated ruler, scale, or measuring container that matches the saved quantity, so your child practices adding cm measurements and noticing how units help compare amounts.
At age six, many kids can count well but still pause when a number has a unit attached. The centimeter label helps your child connect math facts to real measuring language, which matters when first grade work begins asking children to compare lengths, amounts, and totals.
Sit beside your child and read the first problem aloud together. Ask your child to point to the picture, say the centimeter amounts, add the numbers, and write the total with cm, then use the same rhythm for the remaining three problems.
The pictures on the worksheet are models, not life-size measuring tools. The matching illustrations make the page more helpful than a generic number sheet because your child sees the measurement setting while practicing units and comparison in a calm, screen-free way.
