How diagnostic, adaptive practice helps a child work out what to do next — not just do more of the same.

If your child is stuck on maths homework, the advice you'll hear most often is: do more questions. More worksheets, more revision, more practice.
Sometimes that's exactly right. But sometimes it isn't — and it's worth knowing the difference before you spend another evening at the kitchen table over it.
Say your child finishes ten fraction questions and gets six right. That score tells you something happened. It doesn't tell you why the other four went wrong.
Maybe they don't yet understand equivalent fractions. Maybe they're mixing up the numerator and denominator. Maybe they understood the method fine and just rushed the arithmetic. Those are three different problems with three different fixes, and "here's another fractions worksheet" really only solves one of them.
A wrong answer isn't just something to put a cross next to. It's a clue.
Take a child who works out 1/2 + 1/3 and writes 2/5. That's wrong, but it's not random — they've added the numerators together and the denominators together, the way you'd combine two whole numbers. It's a completely understandable mistake, and it tells you exactly what to revisit: how fractions with different denominators actually combine, not "more practice on fractions" in general.
Once you know that, the next question they need isn't a random one from the same worksheet. It's one that checks whether they've actually grasped equivalent fractions and common denominators.
Handing a child the correct answer rarely teaches them how to get there next time. What helps is seeing where their own reasoning took a wrong turn — using their own numbers, not a generic textbook example that looks nothing like the problem in front of them.
That's the difference between marking an answer and actually teaching from it.
If a child gets stuck on a genuinely hard question, throwing another hard question at them straight after usually just produces a second wrong answer and a more frustrated child. It helps far more to step back to the skill underneath it, check that's solid, and then return to the original level once it is. The goal isn't to make things permanently easier — it's to repair the gap so they can get back to where they were stuck, properly ready this time.
None of this means throwing away practice questions — children do need repetition to build fluency. It means being more deliberate about which question comes next, based on what the last one actually showed.
That's the idea behind how Grasp Maths marks and sequences questions: not just right or wrong, but what the answer suggests a learner is ready for next.
Whether your child is working towards SATs, the 11+, GCSEs, or just building solid foundations, the same principle holds: start from what they actually know, find what needs attention, and build from there.
Don't just practise more. Practise what matters next.
