My Child is Behind in Maths — What to Do

Published 13 April 2026 · Merit Tutoring

If you've just come from a parent-teacher conference, or read a school report that made your stomach sink a little — take a breath. Your child falling behind in maths is one of the most common things parents come to us about. And it's almost never as catastrophic as it feels in the moment.

That said, maths isn't the kind of subject where gaps magically close on their own. It builds on itself, year after year. So it's worth understanding what's actually happening before deciding what to do about it.

Why Kids Fall Behind in Maths

Maths is cumulative in a way that most subjects aren't. A child who misses a unit on fractions in Year 4 doesn't just have a gap in fractions — they have a gap that makes percentages in Year 5 confusing, and then ratios in Year 7, and then algebra that involves fractions in Year 8. The original missed concept ripples forward.

This happens more often than most parents realise. The Australian post-COVID learning disruption affected a significant portion of primary school students, and those gaps are still working their way through the year levels. Your child is not uniquely struggling — but that doesn't mean the gap will sort itself out without some help.

There's also the confidence spiral to consider. A child who starts falling behind in maths often starts believing they're just "not a maths person." That belief becomes self-fulfilling. They stop trying, check out in class, and the gap widens. By the time a parent notices something is wrong, the original content gap is often smaller than the confidence problem sitting on top of it.

How to Tell How Far Behind They Actually Are

This is harder than it sounds. Report card grades are a signal, but they're not precise. "Working towards expected level" could mean one topic behind or three years behind — the report doesn't tell you.

A few practical ways to get a clearer picture:

Ask the teacher directly — not "is my child doing okay?" but specifically: "What year-level content are they currently working through? Are there any specific strands where they're notably behind?" Most teachers will give you a straight answer if you ask a straight question.
Try some year-level problems at home. Pull up some free Australian Curriculum maths problems for their year and the year below. Where they start to struggle tells you something. If they can't fluently recall multiplication facts in Year 5, that's a Year 4 gap worth addressing.
Specific red flags by year level: In lower primary, watch for difficulty counting on from a given number, shaky place value understanding, or still needing fingers for basic addition in Year 3+. In upper primary, struggling with times tables by Year 5, or not understanding what a fraction actually represents. In high school, watch for Year 7 algebra being completely opaque — it often means the fraction and ratio concepts from Year 5–6 weren't solid.

What You Can Do at Home

Not everything requires a tutor. There are things that genuinely help, and things that backfire.

What helps: Mental maths at dinner — not drill, just conversation. "If we split this pizza into 8 slices and there are four of us, how many does each person get?" Times tables in the car, framed as a game, not a test. Encouraging your child to explain how they solved something, rather than just checking if they got the right answer. When a child can explain a method, they understand it.

What tends to backfire: Sitting down for extra worksheets when your child is already frustrated with school. Drilling facts under time pressure when the underlying concept isn't there yet. Making maths feel like punishment. If the relationship around maths at home has become adversarial, that's important to know — because more pressure at home will compound the problem, not fix it.

Also: don't do the work for them. It feels kind, but a child who watches you solve the problem has learned nothing except that someone will rescue them.

When to Get Help

The short answer: sooner than feels necessary. The longer answer: when any of the following apply.

The gap has persisted across more than one school term. You've tried helping at home but the homework time has become a consistent battle. Your child has started saying they're "bad at maths" or avoiding maths work. The teacher has flagged concern. Or your child is approaching a year where the cumulative nature of maths makes gaps harder to recover from — Year 7 is a real inflection point.

If you're not sure how far behind your child actually is, Merit's free 60-minute session is a low-pressure way to find out. We assess where they are, work through real content with them, and tell you honestly what we see. You don't have to sign up for anything.

What to Look for in a Maths Tutor

The most important thing is that the tutor starts where the child actually is — not where they should be for their year level. A good maths tutor doing Year 6 content with a Year 6 child who has a Year 4 gap will get nowhere. You need someone who will go back, identify the foundational weakness, and build from there.

Look for alignment to the Australian Curriculum, so the tutoring connects to what's being taught at school rather than working on a parallel track. A live tutor who can respond to confusion in real time — not pre-recorded video. And some form of parent communication, so you know what's being covered and how it's going.

How Gamified Tutoring Specifically Helps With Confidence

We at Merit see this particular pattern constantly: a child arrives with a content gap, but the bigger issue is that they've stopped believing they can do maths. They're defensive. They expect to fail. Getting through to them on content alone doesn't fix that — you have to change the experience first.

That's what the game-based format does. When a Year 5 student plays Balloon Pop to practise multiplication facts, they're not being tested — they're competing. The emotional experience of "I got that right and it felt good" is completely different from the emotional experience of getting a sum wrong on a worksheet. A few sessions of succeeding at something they thought they couldn't do starts to shift the story they tell themselves.

It's not magic. The content has to be right. But confidence without content is hollow, and content without confidence doesn't stick. Both need to move together.
