Lesson Details
Key learning points
- A pie chart is another way of presenting data representing parts of a whole.
- Pie charts can be constructed using knowledge of angles and fractions.
- A protractor is used to accurately measure each angle.
Common misconception
Pupils may make mistakes measuring with a protractor, reading the wrong scale to get a measurement.
Encourage pupils to check that each answer is sensible. Is the angle greater or less than a right angle? Have they drawn an angle greater/less than a right angle? Do all the angles add up to a sum of 360°?
