A pie chart is an excellent way of representing data in a circular graphs/chart when comparing parts of a whole.

The sections of the pie chart are proportional to the size of the data it represents.

In the case of the pie chart to the right, this could represent the following:

5 children in total (5 sections) were asked if they preferred drawing or painting.

3 out of the 5 children preferred drawing (represented by the 3 white sections)

2 children out of the 5 preferred painting (represented by the 2 blue sections).

Pie charts are also an excellent way to introduce children to fractions by representing the same data like this:

3/5 or three-fifths preferred drawing

2/5 or two-fifths preferred painting

This can also be extended in to percentages:

1/5 = 20%

3/5 = 3 x 20% = 60%

2/5 = 2 x 20% = 40%

60% of children preferred drawing

40% of children preferred painting.

Pie charts can also become more challenging as each section is worth more than one.

When children are older, they learn how to draw pie charts of their own.
