Multiplying and dividing fractions, and connecting fractions to division itself — the final pieces of primary fraction learning.

By Year 6, most of the building blocks for fractions are in place: equivalence, common denominators, mixed numbers. This year adds the final operations — multiplying and dividing fractions — and asks children to see a fraction not just as "part of a whole," but as a division calculation in its own right.
Multiplying two fractions is mechanically simpler than adding them: multiply the numerators together, multiply the denominators together, no common denominator required. This surprises some children after the extra work fraction addition demanded in Year 5, and it's genuinely worth pointing out explicitly that the two operations don't need the same process — treating them the same way is a common and avoidable source of unnecessary extra steps.
Dividing a fraction by a whole number — 1/3 ÷ 2 = 1/6 — asks a child to reason about what it means to split an already-small piece into even smaller pieces, which is a genuinely different mental model to multiplication. It's often the last fraction skill to feel secure, and it benefits more than most from a visual model: splitting a third of a pizza into two equal, smaller pieces and seeing that each is a sixth of the whole pizza.
Understanding that 3/8 is the same as 3 ÷ 8 is one of the more abstract ideas in Year 6, but it's genuinely useful — it's what makes converting a fraction to a decimal by division make sense, rather than being a separate rule to memorise. A child who's secure on this connection has effectively unified fractions, division and decimals into one coherent idea, rather than three separate topics that happen to be related.
Applying the common-denominator method to multiplication unnecessarily (treating 1/2 × 1/4 as if it needed the same process as 1/2 + 1/4) is a very common Year 6 mistake, usually because addition was taught and practised more heavily the year before. It's worth explicitly checking which operation a question is actually asking for before applying a remembered process.
Grasp Maths tracks fraction addition, multiplication and division as separate skills, so a child who confuses the methods between operations gets that specific confusion addressed directly, rather than more generic "fractions" practice that doesn't distinguish between them.
