Video summary
In this clip pie charts are introduced and an explanation is given to highlight that they show relative proportions.
There are examples to demonstrate the usefulness of pie charts and how we have an intuitive visual understanding of simple fractions and proportions, which pie charts exploit.
Numerically, the connection between fractions, decimals, percentages and the angles in a pie chart are explained.
The end sketch demonstrates calculating a fraction of a fraction.
This clip is from the series Kick Sum Maths.
Teacher Notes
This clip could be used to revisit fractions, decimals and percentages. A pie chart with some missing information could be used as a starting point, from which to calculate unknowns.
The end sketch (Fraction Karate) leads to calculating fractions of fractions, fractions of percentages, etc.
These clips could be used for teaching Maths at KS2 or at a beginner level in England, Wales and Northern Ireland and 1st and 2nd Level in Scotland.
