pyramid

Definition

A pyramid is a 3D shape with a flat bottom (like a square or triangle) and triangular sides that all meet at a single point at the top. We name a pyramid by the shape of its bottom, like a "square pyramid" if its base is a square.

A block with a square bottom and four triangle sides that meet at a point is a square-based pyramid.

How to teach this in 30 seconds

Try this analogy: A pyramid is like a tent that has a flat bottom and sides that meet at a pointy top.

Ask your child: What shapes do you see on this pyramid?

Common mix-up: Kids might confuse a pyramid with a triangle because of its sides. A pyramid is a 3D shape you can hold, while a triangle is a flat 2D shape.

Examples

  • The great pyramids in Egypt are famous square-based pyramids.
  • A block with a triangle for a base and three triangle sides is a triangle-based pyramid.

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