Check understanding
- Explain the difference between a 'ratio' and a 'proportion' using a concrete example like mixing paint
- Use 'per cent' correctly and convert between fractions, decimals, and percentages in context
- Define 'scale factor' and use it to describe how a shape has been enlarged or reduced
“If your child is sharing something 3 ways and 2 ways, can they explain the difference between a ratio (like 3:2) and a proportion (like 3 out of 5) — showing they know what each word means?”
