volume

Definition

Volume is how much 3D space something takes up, like how much water fills a bottle.

A big, puffy winter coat has more volume than a thin raincoat because it takes up more space in the closet.

How to teach this in 30 seconds

Try this analogy: Volume is like how much space your toys take up inside a toy box.

Ask your child: Which of these two toys do you think takes up more space?

Common mix-up: Kids may think a taller object always has more volume. Volume is about the total space an object fills up, not just how tall or heavy it is.

Examples

  • A tower built with 20 blocks has more volume than a tower built with 10 blocks.
  • A full cup of juice has more volume than a half-full cup.

volume is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
