Multiplying fractions (age 10+)
Multiply a fraction or whole number by a fraction, including proper fractions by proper fractions; interpret (a/b) × q as a parts of q partitioned into b equal parts; write answers in simplest form
Lesson
Set out your lesson
Interpret fraction multiplication as taking a fraction of a quantity, and connect the product to an area model.
Before teaching
Use this short check, then start teaching.
Check that 2/3 of three equal parts and fraction times whole-number examples make sense. Revisit mt_TgHxujL81r if needed; use mt_b7T-CjOYUR when simplification is uncertain. Canonical ages are 10–11, not a readiness guarantee. These activity checks are inferred; source availability is not mastery.
Check learner readiness directly; prerequisite availability is not attainment.

Check understanding
- Compute (2/3) × (4/5) = 8/15 and show with an area model
- Use a visual model to demonstrate (2/3) × 4 = 8/3 = 2 2/3
- Simplify the product 3/4 × 2/3 = 6/12 = 1/2
“If a recipe uses 2/3 of a bag of flour and your child only wants to make 3/4 of the recipe, can they multiply those fractions to find out how much flour they need?”
