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.
