2nd grade estimating length worksheets

Tap to see another sample sheet.

Estimating length worksheets for 2nd grade show eight everyday objects and ask your child to pick the sensible length for each, the way a spoon is closer to 6 inches than 6 feet. The pictures are not drawn to scale, and the sheet says so, so the choice has to come from knowing the object and the unit rather than from measuring the drawing.

The kind of problems you'll get

Choose a sensible estimate for each object. Pictures are not actual size.

  1. Is a spoon closer to 6 inches or 6 feet long?

    Answer: 6 inches.

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.

What's on each sheet

Every version prints on US Letter or A4, with its answer key after the problems.

This sheet is one of the versions on the 2nd grade measuring length page, with its own difficulty choices and its own answer key.

How to teach this

Before the sheet, pick two body benchmarks: a finger width for about an inch and an arm span for a few feet. Then for each object, ask what it is and how it compares to the benchmark. The rule on the sheet says think about the object and the unit, and that second part is where 2nd graders slip. A number can be right for inches and absurd for feet. Have your child say the whole estimate out loud with the unit attached, 6 inches, not just 6. The trap is measuring the picture, since the drawings are not actual size and a spoon can be drawn larger than a chair. For a check, after the eight problems, pick one object you have in the house, guess together, then measure it with a real ruler or tape. Being close counts. Being in the right unit counts more.

Watch for: Kids measure the drawing instead of thinking about the real object, so a spoon drawn large gets 6 feet. The sheet says pictures are not actual size. Ask how long the real thing is when you hold it. Kids pick the right number and the wrong unit because the number looked familiar. Have them say the estimate with the unit and then picture it: a 6-foot spoon would be taller than they are.

Common questions about 2nd grade estimating length

What does my child do on this sheet?
Each of the eight problems shows an everyday object and asks for a sensible estimate of its length, chosen from the options given. Nothing is measured. The pictures are not to scale on purpose, so the answer comes from knowing how big a spoon really is, not from the drawing.
Which units are used?
The worked example uses inches and feet: is a spoon closer to 6 inches or 6 feet? The standard behind the sheet, 2.MD.A.3, covers inches, feet, centimeters, and meters. Part of the task is noticing which unit is on offer, since 6 inches and 6 feet are both a 6.
Is there an easier version?
This sheet comes in one version: eight pictured problems, and each print draws a fresh set of objects. If your child needs a smaller step, the measuring sheets on the parent page put a ruler on the page, and that concrete work is what the estimates are built on.
