1
WALT create designs with rotational symmetry Another of Mrs Robertson’s magical maths lessons!

2
Draw a circle and cut it out.

3
Fold it in half and half again to create 8 segments.

4
Use it as a guide to mark the 8 segments on an identical circle

5
Use a ruler to draw the eight segments.

6
Take a segment cut from one of the original folded circles.

7
Draw a pattern on the segment...anything goes!

8
Scribble pencil on the back of the segment.

9
Lay the pattern in one segment... exactly. Draw over the pattern... It will print!

10
Repeat this on each segment.

11
Start to colour the pattern. Repeating each colour in every segment

12
This pattern has a rotational symmetry of.. 8

13
Extension activity Further investigations...

14
By colouring alternate segments in identical colours..

15
This pattern has a rotational symmetry of.. 4

16
Try colouring alternate segments...

17
This pattern has a rotational symmetry of.. 2

18
Well done! You have created designs with rotational symmetry Hope you enjoyed another of Mrs Robertson’s magical maths lessons!
