Centimeter Comparison Worksheet

Five-year-olds often guess when two measurements look close, especially when the numbers are new. On this printable page, they work through four centimeter comparison problems by looking at the shown cm amounts and the matching picture models, then deciding how the measurements compare.

This page is a good fit when a child can count and recognize written numbers but still needs practice using them in measurement. They do not need to measure real objects on the page. The pictures are models, not life-size measuring tools, so the goal is to read the shown quantities and compare them.

Sit beside them and move one problem at a time. Point to the cm label, read both amounts aloud, and ask, “Which measurement is longer?” or “How do you know?” If they guess, have them cover one problem, compare just the two numbers, then look back at the picture model to check their thinking.

For a next step, try kilogram comparison practice so they can compare a different kind of measurement. When they are ready to combine measures instead of just comparing them, the pint addition measurement page gives a gentle move into adding units.
