About this worksheet

Pictures of everyday things, like a key, an egg, a bike and a horse. Circle the better unit.

What kids practice

Mass is how heavy something is. Liquid volume is how much a container holds. Third graders measure mass in grams (g) and kilograms (kg), and liquid volume in milliliters (mL) and liters (L). They pick the better unit, read scales and measuring cups with marked steps, and solve one-step word problems with these units.

Watch for

  • Counting each mark as 1 when the marks count by 2s, 5s, 10s or more.
  • Picking the unit by the size of the thing instead of how heavy it is. A balloon is big but light.
  • Mixing up mass and volume words, like saying a cup weighs 250 milliliters.

It's free to print, with Fewer, Standard or More on the page and an answer key. See the full mass and volume guide for 3rd grade.
