Make Capacity Estimation Easy for Kids

When teaching metric or customary capacity encourage students to bring in containers with different capacities.  Have students cover up the amount that the container holds and allow their peers to guess what the container holds in both metric and customary measurements.  For example, bring in a soda can, a water bottle, liquid soap bottle, etc.  If students’ guesses are extremely unreasonable, allow the student holding the container to tell their peers higher or lower.  After a few students bring in containers, the enthusiasm in the classroom grows and more students will contribute to the classroom capacity collection.
