Math Experiments: Capacity

Welcome to our lesson on capacity! We read the book Capacity** together and gathered containers together to compare capacity. We decided to use only clear containers so that we could see the water very clearly.

First, the boys filled each container with water. Ezra used a 1 cup plastic measuring cup that we usually use in our rice sensory box, and Ender used the small pitcher we usually keep in the fridge so that they can pour their own drinks. We had a sponge and a towel on hand just in case of spills!

Ender estimated which glasses held different amounts of water from greatest to least, and we lined them up in that order.

Ender poured each container into a 4 cup measuring cup and measured each amount to see how his estimations worked out.

We learned that "tall" doesn't necessarily equal "most".

** We love this series of math books by Henry Pluckrose. Our library has most of them and they've been a really fun way to introduce new concepts.
