Lesson details
Key learning points
- A smaller percentage of one number can be greater than a larger percentage of a different number.
- Proportionality offers another way to compare values.
- One way, in isolation, does not give a full picture.
Keywords
Proportionality - Variables are in proportion if they have a constant multiplicative relationship.
Common misconception
Pupils only see the amount, not proportion. e.g £30 from £100 is no different to £30 from £60.
Referring to the whole using bar models or fractions can emphasise the amount with respect to the whole.
