For example
A cooking pot has a bigger capacity than a tea cup.
In Grade 2
Children pour water between containers to see which holds more, before any unit is named.
Watch out for
Children often judge capacity by height alone. A tall thin bottle can hold less than a short wide pot.
Say it at home
Pour from one container into another at the sink and ask which one holds more.
Younger children may meet this as: how much it holds.
