Centimeter Subtraction Measurement Worksheet

Kids often know how to subtract small numbers, then stall when a unit like centimeters is attached. This page keeps the work focused: four measurement subtraction problems in cm, each paired with a picture model that matches the quantities in the problem.

This is a good fit for a 6-year-old who can read simple subtraction sentences and is starting to notice units in measurement problems. The pictures help make the saved quantities easier to talk about, but they are models, not life-size measuring tools. Your child does not need to measure the printed pictures with a real ruler.

Have your child read one problem at a time, point to the matching model, subtract the numbers, and write the difference with cm. If the unit gets left off, ask, “Centimeters of what?” That small prompt helps connect the number answer to the measurement idea without turning the page into a long lesson.

Sit nearby for the first problem and let the next ones be a little more independent if your child is ready. For a simple next step, compare answers aloud by asking which difference is longer or shorter. When centimeter subtraction feels comfortable, try another measurement page with liquid units, such as the milliliter addition measurement worksheet, or practice customary capacity with the pint addition measurement worksheet.
