What it is
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.
What comes next
Scaled graphs and line plots.
How to teach it
- Hold a paper clip (about 1 gram) and a bag of flour or a big book (about 1 kilogram).
- Fill a 1-liter water bottle and pour it into cups to see how much a liter is.
- Read the labels on food packages for grams and milliliters.
- On a scale or cup, find what each little mark is worth before reading it.
- Weigh things on a kitchen scale and guess first.
Common mistakes
- 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.
