Add Measurements in Centimeters

This centimeters measurement worksheet presents four addition activities using length amounts in the same unit. Combine the two printed amounts and write each total. The page also includes a measurement mission asking for one more answer and an explanation. Read the unit abbreviation cm as centimeters before beginning.

Use the supplied numbers and illustrated measurement models to work through one example together: 6 cm + 3 cm = 9 cm. Keep the unit with the numbers while explaining how the two amounts are combined or separated. The picture rulers represent the given amounts; they are not printed at actual measuring size. All comparisons and calculations on this page use centimeters.

An adult can read a prompt, ask what is known, and let the child explain the next step before writing. The measurement mission asks the child to combine 6 cm and 3 cm. Use counting objects or a drawn number line on separate paper if the arithmetic needs support. Then return to the measurement wording and say what the answer represents.

Find other units and operations in the Measurement Workshop Pack. For practice with ordinary number operations, explore the Addition and Subtraction Pack. A separate hands-on follow-up can use a suitable measuring tool with adult guidance. Keep that real measurement activity distinct from the worksheet’s supplied values, and begin with a few problems that the child can explain comfortably.
