- Definition
Symmetry means that if you fold a shape along a line, or spin it around a point, both halves would match up perfectly.
A drawing of a butterfly shows symmetry because the pattern on the left wing matches the pattern on the right.
How to teach this in 30 seconds
Try this analogy: Symmetry is like a butterfly's wings, where one side is a perfect mirror image of the other.
Ask your child: What happens if you fold this shape right down the middle?
Common mix-up: Kids might think symmetry just means something is balanced or has two halves. The key is that the two halves must be exact mirror images of each other.
Examples
- A simple drawing of a face has symmetry, with one eye on each side of the nose.
- Folding a paper in half and cutting a shape creates a symmetrical design when you open it.
symmetry is a term used in Ontario’s Kindergarten to Grade 8 curriculum.
