face

Definition

A face is simply one of the flat sides of a 3D shape, like the front of a box.

A cube has six flat surfaces, so it has six faces.

How to teach this in 30 seconds

Try this analogy: A face on a shape is like the flat side of a toy block you can press your palm against.

Ask your child: How many flat faces can you count on this box?

Common mix-up: Kids might think any surface is a face, like on a ball. A face is a flat surface, not a curved one.

Examples

  • A cereal box has a front face, a back face, and side faces.
  • A can of soup has two flat faces on the top and bottom, but its side is curved, not a face.

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