Never judge a book by its cover or a container by its height, While it may appear counterintuitive that a tall, skinny cylinder holds less than a short, wide one, experimenting with containers can help your child build confidence with their understanding of volume and capacity.
Explore this idea with your child using containers at home. Get them to play around with different-sized and shaped containers to explore how the shape and size of a container can influence what we think its capacity could be.
