How to Tell if Your Child Actually Understands What They're Learning

A correct answer proves surprisingly little. Here's how to find out what's underneath it.

A tick tells you the answer was right. It doesn't tell you whether anybody understood anything.

A correct answer can mean four completely different things. They understood it. They remembered a method. They copied the example above. Or they guessed and got lucky.

All four look identical on the page, which is why homework can be full of ticks while nothing much is going in.

The only reliable way to tell them apart is to ask them to explain — and there are five questions that do it, none of which take longer than a minute.

1 “How did you work that out?”

The single most useful question a parent can ask, and it appears in almost every article in this series for good reason.

It works because it's not checkable from the page. A guess can produce the right number; it can't produce a method.

Listen to the shape of what comes back. Confident and structured means understanding. Vague, or a method recited with no idea why, means something worth going back to.

2 “Can you explain it to me?”

Pretend you don't know — genuinely pretend, don't nod along. Being taught is a much better test than being answered.

Explaining forces a child to put their understanding into an order and into words, which is where the gaps show up. They frequently discover a hole themselves halfway through, which is worth more than you finding it for them.

Children love being the one who knows, and it inverts the whole homework dynamic for two minutes. If they get stuck teaching it, that's your answer — and they found it, not you.

3 “Can you give me another example?”

Understanding transfers. Memory doesn't.

A child might know that 50% means half because they've been told forty times. Ask what 50% of £30 is, then where else they've seen 50% this week, and you find out very quickly whether the idea exists outside that one sentence.

After anything they've just got right, ask for one more of their own invention:

“Make me up a different one like that.”

Inventing an example is much harder than answering one, and it's almost impossible to fake.

4 “What would happen if I changed this?”

Take the thing they just did and alter one part of it. Bigger number. Different operation. One word swapped in a sentence.

If their understanding survives the change, it's real. If it collapses, they'd learned the specific question rather than the idea — which is genuinely useful to know, and completely invisible on a marked page.

5 “What makes you think that?”

The English and everything-else version, covered properly in article 05.

Where “how did you work that out?” asks for a method, this one asks for a reason — a bit of evidence, something in the text, a because. It works on reading, history, science, and any opinion offered at dinner.

Both questions do the same job: they move a child from producing answers to defending them.

The one that settles it

“Can you teach it to me?”

If you only use one of the five, use this. Hand them a pen and a piece of paper and be a slightly dim student.

Ask the annoying questions a real learner would ask. “Why do you do that bit?” “What if it was a different number?” “Wait, where did that come from?”

You will find out in about ninety seconds which parts are solid and which parts are recited. There is no faster diagnostic and it costs nothing.

And children enjoy it far more than being tested, because for once they're the one who knows.

The Secondary School Ready checklist

One page, on the fridge. Every “try this” from across the series, so you've got them when you need them. Free, no strings.

One email with the checklist attached. Occasional tips afterwards, and you can unsubscribe in one click. We never pass your address to anyone.

Don't turn it into an interrogation

Five questions in a row is not a conversation, it's a viva, and children shut down fast. This isn't meant to become the Parent Examination Board.

Use one, naturally, and then let it go. At dinner. In the car. During something they're already doing. Once every day or two is plenty.

What you're building isn't a testing regime — it's a household where explaining your thinking is a normal thing to be asked to do. That habit is worth far more than any individual answer you'll get.

Where MindBlaze fits

Practice shows you what a child can do. It doesn't, on its own, show you whether they understand it — which is exactly why the Learning Centre exists alongside the daily missions.

Missions find the gaps. Explanations fill them. A child who gets something wrong needs to see why, not simply be marked and moved on.

Both halves are necessary, and the second one is the half most practice apps leave out.
