Lesson details
Key learning points
- Addition, subtraction, multiplication and division can be used to calculate a new percentage from known percentages.
- For example, if I know 10% of a number, I can halve it to find 5%
- If I know 10% and 5% of a number, I can add them to find 15%
Keywords
Efficient - Efficient means working in an organised way without wasting time or effort.
Percentage - A percentage is a proportion of a whole.
Common misconception
Pupils may find calculating 75% of a number difficult.
First focus on teaching one strategy for finding 75% of a number. Pupils may find it easiest to add 50% and 25% together. Show representations of this (e.g. bar models showing the proportion of the whole) alongside calculations.
