Third graders learn to measure mass (how heavy) in grams and kilograms, and liquid volume (how much) in liters and milliliters — and to estimate which unit fits, from a paper clip to a full water bottle.
Students will be able to…
A paper clip and an elephant both have mass — but you’d never measure them the same way! How do we measure how heavy something is, and how much a container holds?
Project this and tap each idea about mass and volume. Practice estimating which unit fits each object!
