How to do it
- Look where the thing starts at 0.

About this worksheet
Things lined up on a centimeter ruler, from 3 to 16 centimeters long.
What kids practice
Second graders learn to measure with a real ruler, in inches and in centimeters. They line the end of the object up with 0, read the number at the other end, and write the unit. They also learn that the same pencil is more centimeters long than inches long, because a centimeter is smaller, and they compare lengths by subtracting.
Watch for
- Starting at the edge of the ruler or at 1 instead of at 0.
- Counting the tick marks instead of reading the number.
- Forgetting to write the unit.
It's free to print, with an answer key. See the full inches and centimeters guide for 2nd grade.
