# Lines of symmetry

I can identify shapes and images that have reflective symmetry and explain where the line of symmetry lies.

# Lines of symmetry

I can identify shapes and images that have reflective symmetry and explain where the line of symmetry lies.

## Lesson details

### Key learning points

- A line of symmetry is used to show that one half of a shape is a reflection of the other half.
- When an image is folded along a line of symmetry, the two halves will match.

### Common misconception

Children may think that any line drawn down the middle of a shape is a line of symmetry.

It is important for children to see that a line of symmetry can be folded to give two halves that match - one half is a reflection of the other half. Explore folding cut-outs of symmetrical and asymmetrical shapes to find lines of symmetry.

### Keywords

Line of symmetry - If you were to fold a shape on its line of symmetry, both halves would match exactly.

Reflection - An image or shape as it would be seen in a mirror.

Symmetrical - When a shape has a line of symmetry, it can be described as symmetrical.
