Lesson details
Key learning points
- In all of these representations a single multiplier can be used to find a percentage increase.
- Representation can help when you are not using a calculator.
- A multiplier is significantly faster when using a calculator.
- To increase, you are going above the original amount.
Keywords
Proportion - If two things are proportional then the ratio of part to whole is maintained and the multiplicative relationship between parts is also maintained.
Common misconception
A single digit percentage is incorrectly worked out by dividing by 10 and not 100 e.g 3% = 0.3. This error continues when increasing amounts e.g increase 40 by 3% has a multiplier of 1.3
Remind pupils that to covert a percentage into a decimal we divide by 100. This applies with increase too e.g 120% has a multiplier of 1.2
