What does my child actually do on the sheet?

Each item shows a shaded bar above a printed ruler. Your child reads where the bar ends and writes the length with its unit, like 5 in or 8 cm.

Are the answers whole numbers?

Yes. Second grade bars always start at 0 and land exactly on a whole inch or centimeter mark, so the answer is simply the number at the end of the bar.

2nd grade measuring length worksheets

Measuring length worksheets for second grade put the ruler on the page: a shaded bar sits above it, and your child reads its length in whole inches or centimeters. Every bar starts at 0, so the answer is the number at the end mark.

The kind of problems you'll get

Use the pictured ruler to find each bar’s length. The pictures are not actual-size rulers.

A bar runs from 0 cm to 5 cm. How long is it?
Answer: 5 cm.

Most problems on this sheet sit beside a picture, model or diagram, so this is the worked example the sheet itself prints. The answer key on page two prints the answer under every problem.

Every print pulls a fresh set of problems at this level, so a make-up test or a second sibling never gets the same sheet.

How to teach this

Have your child put a finger on the 0 first, then slide to where the bar ends and say the number out loud. If answers come out one too high or one too low, they are probably counting tick marks. Count the spaces between marks together instead. Alternating between the inch sheets and the centimeter sheets keeps the unit label part of the answer, not an afterthought.

Watch for: Kids count the tick marks instead of reading the number at the end. The length is the number where the bar stops, not how many lines it crosses. Kids read the end tick even when the bar starts at a nonzero mark. Count the span from start to end, or subtract the start number from the end number.
