Centimeter Comparison Worksheet

Kids can understand “bigger” and still stall when a measurement unit is part of the problem. This printable gives a first grader four centimeter comparison problems. They read the centimeter quantities shown by the illustrated models, then decide how the two amounts compare.

The pictures on the page may look like rulers, scales, or measuring containers, but they are models, not life-size tools. Have your child use the numbers, marks, and cm labels printed on the page instead of measuring the artwork with a real ruler.

This is a good fit when a six-year-old can read the numbers in the problems and understands everyday comparison words like greater, less, and same. Sit close for the first item. Ask, “What does each side show in cm?” Then have them point, read, and write or mark the comparison answer.

If the page feels too busy, cover three problems with a sheet of paper and do one at a time. For a next step with another length unit, try the feet comparison worksheet. When your child is ready to combine measurement with subtraction, the pint subtraction measurement worksheet gives practice with a different unit in a simple problem format.
