Design your own Pie chart to show your understanding. This can be based on anything. For example your favourite sport or colour. Things to remember: Create your table. Make sure your frequency can be added together and then divide 360 by the sum. Work out the angles. Measure the Angles. Don’t forget to label your diagram.

Extension: Worksheet with tables already drawn where pupils have to figure out the angle for themselves.
