Measure Lengths in Centimeters: what children learn

Measuring starts at 0 on the ruler, and the number where the bar ends is its length in centimeters. These rulers go up to 30, so kids practice reading longer lengths.

Measure Lengths in Centimeters: how to help at home or in class

Cut a piece of string, hold it flat against a centimeter ruler, and read its length. Snip off a bit and measure it again, so your child sees the number shrink. For lengths past 10, tape two paper rulers end to end or use a long tape, and have your child say the tens before the ones. Once readings up to 30 come easily, move on to comparing two lengths.
