Before your child can divide fractions: the 3 things they need first (Class 6)
Before a child can divide fractions, they need three things: a fraction understood as a quantity rather than two numbers, division understood as "how many of these fit into that", and confident multiplication of fractions. Flipping the second fraction is a shortcut, not the idea. A child with only the shortcut passes Class 6 and stalls in Class 8.
What dividing fractions actually requires
Dividing fractions is the first place in school maths where the procedure and the meaning come apart badly. "Flip and multiply" is easy to remember and impossible to justify, so most children learn the rule and quietly stop asking what it means. These three things are what the rule is standing on.

What a fraction actually means
Class 4
Your child has to see 3/4 as one quantity sitting between 0 and 1, not as a 3 and a 4 with a line between them. If a fraction is still two numbers, then dividing one by another is two operations on four numbers, and no explanation will land.

Long division, conceptually
Class 5
Not the algorithm — the question. Division asks how many of one thing fit inside another. A child who only knows division as "the opposite of times" has no way to make sense of 2 ÷ 1/4, because nothing about it looks like a times table.
-
Multiplying fractions
Class 6
Flip-and-multiply ends in a fraction multiplication. If that step is shaky, the error shows up at the end and looks like a division mistake, which sends everyone hunting in the wrong place.
You may also want to check equivalent fractions, because simplifying the answer is where a correct division often turns into a wrong final line.
How to check in five minutes
Ask these tonight, on paper, and ask your child to say their reasoning out loud. You are not marking the answer. You are listening for whether there is a reason behind it.
How many quarters are there in 2?
"Eight — four in each one, and there are two." Answered as a counting question, without writing anything down.
They write 2 ÷ 1/4, flip it, and compute. The answer is right but the question was never understood as a question — it was matched to a procedure.
Is 6 ÷ 1/2 bigger or smaller than 6? Don't work it out — just say which.
"Bigger, because halves are small so lots of them fit." The size of the answer is predicted before any arithmetic.
"Smaller — dividing makes things smaller." This is the single most common misconception at this age, and it survives untouched through years of correct answers.
Why do we turn the second fraction upside down?
Any answer that refers to how many fit in, even clumsily. "Because there are two halves in every one, so you get twice as many" is a complete understanding.
"Because that's the rule" or "because Ma'am said". Not laziness — they have genuinely never been given a reason, and they have stopped expecting one.
The three ways children get this wrong
What to do if there's a gap
Do not go back to the beginning of fractions. Go back to the one idea that failed the check above, and only that one.
If the gap is "dividing makes things smaller", it is fixed with objects rather than explanation. Cut a chapati into halves and ask how many pieces there are. Then quarters. Let them notice that the pieces get smaller while the count goes up. That contradiction is what has to be felt, not told — a child can repeat the correct sentence back to you the same evening and still believe the old thing a week later.
If the gap is "because that's the rule", the fix is to stop asking for answers for a while and start asking for reasons. It is slower and it feels like going backwards. It is the only thing that transfers.
The same shape of problem — a rule that works for two years standing in place of an idea — turns up again with negative numbers in the same class. If you are not sure which of the three gaps you are looking at, that is exactly what the thinking diagnostic is for.
Questions parents ask
Why do we flip the second fraction when dividing?
Because dividing by a number and multiplying by its reciprocal are the same question. Dividing by 1/2 asks how many halves fit into something, and there are twice as many halves as wholes, so you multiply by 2. The flip is the consequence, not the rule.
My child gets the right answer but cannot explain it. Is that a problem?
Yes, though not an urgent one in Class 6. A child who applies flip-and-multiply correctly will keep scoring well until roughly Class 8, when algebraic fractions arrive and the procedure no longer matches the question. The explanation is what carries forward, not the procedure. We wrote about this distinction in understanding versus pattern-matching.
Should I reteach fractions from the beginning?
Almost never. Find the one earlier idea that is missing and fix that. Starting again from the beginning is slow, it tells your child they have failed, and it usually repeats the same explanation that did not work the first time.
