About this worksheet

A one-page Year 6 check on pie charts, with the answer key on page 2. A chart shows the favourite colours of 60 people, with red 1/2, blue 1/3 and green 1/6, and three questions ask how many chose each. Pupils then find 25% of 80 and work out the sector angles for 45 pupils who chose football, swimming or tennis in groups of 15, 20 and 10. The last item asks pupils to tick true or false for A bigger sector always means more people, even across two different charts. It follows England National Curriculum statistics for Year 6.

One gap for 25% of 80 people, then a table of football 15, swimming 20 and tennis 10 where pupils write the angle for each.

True or False

A single statement about sector size across two charts, with True and False boxes to tick.

Answers

The numbers for each colour, the percentage answer, the 8ยฐ per pupil working with the three angles, and a short reason for the false statement.

How teachers use it

End of topic

Give it at the end of a pie charts unit. Fifteen minutes covers all six questions, and the key on page 2 makes it quick to mark.

Spot the gaps

Question 5 shows who knows the angle method. Pupils who write 15, 20 and 10 have not yet worked out the angle for one pupil.

Discussion starter

Take question 6 as a class vote before pupils tick. Ask for a counter-example, using two charts with different totals.
