Percentages (age 9+)
Know and use the vocabulary of ratio and proportion — ratio, proportion, percentage, scale, equivalent, unequal, relative size, part-to-part, part-to-whole, and out of — and understand the difference between ratio (comparing parts to parts) and proportion (comparing a part to the whole)
Lesson
Set out your lesson
“Percentages (age 9+) means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.”
Bring to the table
- 100-square grid or 10×10 paper
- Pencil
Extra for the adult
Worked example. 25 shaded squares out of 100 is 25%.
Optional challenge. For Percentages (age 9+), add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Percentages (age 9+), not mastery.

Percentages (age 9+) means practising the idea at the table with counters or paper models and one clear check. We will demo once, then your child tries.
Materials: 100-square grid or 10×10 paper; Pencil. Adult shades 25 squares and says 25%. Child shades three percent amounts and names each percent. Done: three correct percent names for shaded parts. Stop after the fresh check; keep optional challenge for another day.

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?”
