About Choosing the Right Unit

What this skill is

Choosing the appropriate unit requires selecting an efficient measurement scale (such as measuring a pencil in inches, a football field in yards, and a road trip in miles) to avoid unwieldy numbers.

When children learn it

Selecting appropriate tools and units for measurement tasks is taught in 2nd and 3rd grade (CCSS 2.MD.A.1, 3.MD.A.2).

Teaching Tips

  • Play the "Silly Units" game: ask your child "Would you measure our road trip to Grandma's house with a foot ruler?". They will laugh and say NO! Ask what they would use instead (miles). Silly questions highlight sensible unit choices.

Common Mistakes

  • Choosing tiny units for giant objects (measuring swimming pool water in teaspoons).
  • Choosing giant units for tiny objects (measuring an insect in meters).
  • Mixing unit types, such as picking pounds for distance or inches for weight.
