Centimeter Addition Measurement Worksheet

Measurement can feel fussy at first, especially when a child is trying to add numbers and remember the unit at the same time. This page keeps the job small with four centimeter addition problems. The pictures show saved quantities with illustrated rulers, scales, or measuring containers, and the child writes the total for each problem in cm.

This is a good fit when a first grader can count on, add small numbers, and recognize that cm stands for centimeters. The pictures are models, not life-size measuring tools, so the task is to read the shown quantities and add them, not to measure the printed artwork with a real ruler.

Sit together and read one problem at a time. Ask, “What is the first centimeter amount?” and “What is being added?” Then let your child count on or use a quick number sentence before writing the answer. If they forget the unit, point back to the label and have them say the full answer aloud, like “twelve centimeters.”

After the four problems, a simple next step is to compare measurement amounts in another unit with this milliliter comparison worksheet, which shifts the focus from adding to deciding which amount is greater. If subtraction is ready next, try the feet subtraction measurement worksheet so the same measurement idea shows up in a different operation.
