Pie chart - A pie chart is a circular graph where sectors represent different groups in proportion to each other.
Sector - A sector is a part, or ‘pie-slice’ part, of a pie chart.

Common misconception

Pupils may make mistakes converting an angle of a sector into a percentage.

Choose to work with angles that can easily be converted into percentages (e.g. 72° is equal to 20% of the whole chart). You could have these readily available in the classroom as part of a display to refer to throughout the lesson.

Pupils need to be familiar with measuring angles and be confident interpreting and using fractions and percentages prior to starting this lesson. Within the lesson, children briefly explore the terms radius, diameter and circumference. These terms can be used to describe parts of the chart.
