Investigate symmetry and symmetrical patterns
I can find lines of symmetry in real life contexts and design my own symmetrical patterns.
Investigate symmetry and symmetrical patterns
I can find lines of symmetry in real life contexts and design my own symmetrical patterns.
Lesson details
Key learning points
- There are lots of real life examples where you can find lines of symmetry, for example in flags.
- When a pattern is symmetrical, you can fold along its line of symmetry and the two halves will match exactly.
Common misconception
Children may think that a rectangular flag has diagonal lines of symmetry.
Allow children to cut out and fold the flags to help them see that a rectangle does not have any diagonal lines of symmetry.
Keywords
Symmetrical - When a shape, pattern or image has two halves that match exactly when folded, it can be described as symmetrical.
Line of symmetry - If you were to fold a shape at its line of symmetry, both halves would match exactly.
Reflect - When you reflect a shape, you flip it over a mirror line or line of symmetry without turning it or changing the size.
