Multiplying fractions (age 11+)
Interpret fractions and percentages as operators — find a fraction or percentage of an amount by multiplying, understanding that 'of' means multiply (e.g., 3/4 of 200 = 3/4 × 200 = 150)
Lesson
Set out your lesson
“Multiplying fractions (age 11+) 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
- Tally sheet or simple bar/dot sketch
- A short set of category counts
Extra for the adult
Worked example. Cats 4, dogs 2 — cats have more. The tally and comparison are the proof.
Optional challenge. For Multiplying fractions (age 11+), add one harder example after success.
What to notice. Keep one parent note: examples tried; results; support used. This session samples Multiplying fractions (age 11+), not mastery.

“If a £120 jacket is reduced by 35%, can your child work out the sale price — by first calculating 35% of £120 and then subtracting?”
