When Your Child Can Do It on Screen but Not on Paper

25 August 2026 · by Larry

She gets nearly everything right on the tablet. Streaks, stars, ninety per cent on a topic she was stuck on last month. Then the school worksheet comes home and half the page is red, on questions that look like the ones she has been getting right all week.

The first thought is usually that the app is too easy, or that she has been guessing. Occasionally that is true. Far more often the maths is genuinely there and something else is missing — and it is worth knowing what, because the fix is small and it is not "more practice".

Four things a screen does that a worksheet does not

1. It often lets her recognise instead of produce. Choosing the right answer from four is a different task from writing one into an empty box. Recognition is easier and it arrives earlier. A child can reliably pick 42 out of a list some weeks before she can reliably produce 42 with nothing on the page to prompt her.

2. It tells her immediately whether she is right. That is the best thing about practising on a screen and it is also what makes paper feel so different. On a tablet a wrong answer is caught in a second. On a worksheet nothing stops her, so an early slip carries down the page, and a mistake she would have corrected instantly becomes six wrong answers.

3. It shows one question at a time. A page of twenty-five is not just twenty-five of those. It is a stamina task and a planning task: where to start, what to skip, how long to spend, when to move on. None of that is arithmetic, and none of it is practised by tapping through questions one at a time.

4. It rarely asks her to set out her working. In a Singapore paper, marks live in the method as much as in the answer. A child who has done all her practice mentally, tapping answers in, has not been practising the part the marker is actually reading. That is one of the most common ways a right answer still loses marks — the wider version of that problem is in right answer, but the marks still went.

So what is the app actually good at?

Recall and fluency. Getting the number facts fast and automatic, so that when she meets a two-step problem her head is free to think about the problem rather than about seven times eight.

That is real and it matters — the child who is still working out the multiplication has nothing left over for the reasoning. But it is one part of the job, and it is not the same part as sitting a paper. Anyone who tells you an app replaces a worksheet is selling something.

Five small things that close the gap

1. Move the last five questions onto paper. Same session, same topic, same difficulty — just a blank page and a pencil at the end of it. Nothing else changes, and the change in what you can see is immediate.
2. Ask her to write the working for one question she got right. Not a wrong one. A right one, so it is not a punishment. You will learn more from how she sets out a question she understands than from anything else you could do in five minutes.
3. One whole page in one sitting, once a week. Not a paper a night. The point is practising the stamina and the pacing, not the sums, so one page done properly beats four done tiredly.
4. Teach the check, not the answer. Read the question again at the end. Does the answer make sense — is it bigger or smaller than it should be, is it the thing that was asked for? A child who checks catches her own slips, which is the whole skill that a screen quietly does for her.
5. Watch her do one question instead of marking ten. Sit next to her, say nothing, and watch. Where she hesitates and what she reaches for tells you more than the ticks and crosses ever will.

Before you decide it is carelessness

It usually is not, or at least not in the way the word suggests. Most of what gets labelled careless has a specific cause underneath it — a step that is not automatic yet, a habit of copying down the wrong digit, a rush at the end of the page. Those are all fixable once you know which one it is, and what careless mistakes usually turn out to be goes through them one at a time.

And if the questions she stalls on are the ones with a story attached rather than the plain sums, this is a different gap entirely and it wants a different answer — see word problems, when the sums are fine but the story is not.

What not to do

Do not buy more assessment books. If the gap is setting out and stamina, another book of the same questions gives her more of the thing she is already good at and none of the thing she is not.

Do not take the tablet away either. Losing the fluency practice to fix a paper-skills problem trades one gap for another, and it turns something she was doing willingly into something taken from her.

And do not mark the page in front of her while she watches. If homework is already tense, checking maths homework without a fight is worth reading first.

One honest note about this site

StudyLab is a screen. Everything above applies to it too.

It does deliberately set every sum out in column form, digits lined up the way they would be on paper, so the layout a child sees here is the layout a marker expects. On the upper-primary problems it also shows the working and explains why the method gets there, because a lucky guess and real understanding look identical without it.

But it will not teach her to manage a page of twenty-five questions with a clock running. Nothing on a screen will. That is what the blank page at the end of the session is for.
