Khan Academy, IXL, Prodigy, and Mathletics are used by millions of Australian families — but Grattan Institute research shows 1 in 3 children still don’t meet grade-level maths expectations after primary school. The problem isn’t the platforms. It’s that practice without diagnosis doesn’t fix gaps.
Why Are So Many Parents Searching for Maths Help Online?
The search data tells a clear story. Thousands of Melbourne parents type “maths online,” “Khan Academy math,” and “IXL” into Google every week. They’re not browsing — they’re worried.
Here’s what’s driving that worry: according to the Grattan Institute’s 2025 survey of 1,745 Australian teachers, only 46% say there is agreement in their school about how maths should be taught. Just two-thirds say their school has mapped out what to teach each term. And only 1 in 4 primary teachers agreed that all students at their school are taught maths by a teacher with strong subject knowledge.
When schools are this inconsistent, parents step in. They download IXL. They set up Khan Academy accounts. They let their child play Prodigy for 30 minutes after dinner and hope the dashboard turns green.
The intention is good. The approach has a critical flaw.
What Online Maths Platforms Actually Do (and Don’t Do)
Let’s be honest about what these tools are. After 25 years working with Melbourne families at Spectrum Tuition, I’ve seen every platform parents bring through our doors. Here’s the reality:
Khan Academy is exceptional for explanation. It’s free, comprehensive, and covers Australian curriculum content from Year 1 through to senior secondary. If your child missed a concept in class, Khan Academy can explain it clearly. What it cannot do is tell you which concept your child missed. The parent or child has to already know where the gap is.
IXL is built for drilling. It adapts difficulty based on performance and provides granular analytics. But Common Sense Media’s 1,607 parent reviews tell a different story: the overwhelming consensus is that IXL creates “more stress than learning,” with parents reporting frustration, humiliation, and anxiety — particularly from the scoring system that penalises mistakes harshly. A child who already lacks confidence in maths does not need a platform that punishes wrong answers.
Prodigy gamifies maths practice into an RPG adventure. Kids enjoy it — 91% of surveyed parents say their children like using it. But engagement isn’t the same as learning. A child can battle monsters for an hour and still not understand why they can’t add fractions. The game rewards participation, not comprehension.
Mathletics and Education Perfect are widely used in Australian schools. They provide curriculum-aligned practice and teacher-assigned tasks. They’re useful supplements — but again, they’re practice tools, not diagnostic ones.
Every one of these platforms shares the same blind spot: they assume the user already knows what needs fixing.
The Diagnosis Problem No Platform Talks About
Here’s what I’ve learned from assessing over 50,000 students across Spectrum’s 15 Melbourne campuses: most children who are struggling in maths don’t have a “maths problem.” They have a gap problem.
A Year 6 student who can’t do long division probably doesn’t understand place value — a Year 3 concept. A Year 8 student failing algebra likely has multiplication fluency gaps from Year 4. Maths is ruthlessly cumulative. Miss one foundational concept, and everything built on top of it wobbles.
Online platforms teach to year level. A Year 6 child on IXL gets Year 6 questions. If the underlying problem is a Year 3 gap, the platform cycles through Year 6 content the child isn’t ready for — building frustration, not fluency.
This is why we built our free online assessment as the first step for every family. It takes 20 minutes and pinpoints exactly where your child’s maths foundations sit — not based on year level, but based on actual ability. A Year 6 student might be assessed at a Year 4 working level in number sense but Year 7 in geometry. That specificity matters.
Why “Practice More” Is Often the Wrong Advice
The standard recommendation from every comparison article online is: “use Khan Academy for learning, IXL for drilling, and Prodigy for engagement.” It sounds logical. But it assumes the child’s problem is insufficient practice.
For roughly half the students we assess, the problem isn’t practice volume — it’s that they’re practising the wrong things at the wrong level.
At Spectrum, we use our 5-Band Model to group students by ability, not age. The bands — Earth, Water, Fire, Air, and Aether — represent distinct stages of mathematical development. An Earth-band student is building foundational number sense. A Water-band student is developing procedural fluency. A Fire-band student is consolidating and applying. Air and Aether students are extending and excelling.
A Year 5 student assessed at Earth band doesn’t need Year 5 content delivered more engagingly. They need explicit, sequenced instruction at the level where their foundations actually sit — delivered by a teacher who can watch their working, catch misconceptions in real time, and adjust the lesson on the spot.
No algorithm does this. Not yet.
When Online Platforms ARE the Right Choice
I’m not here to tell you Khan Academy is useless. That would be dishonest.
Online maths platforms work well when:
- Your child’s gaps are small and recent (missed a week of school, didn’t understand one specific topic)
- Your child is self-motivated and already knows what they need to practice
- You’re using the platform alongside a clear diagnosis of where the gaps are
- Your child is in the Fire, Air, or Aether bands — already above grade level and wanting enrichment
Online platforms are the wrong tool when:
- Your child has cumulative gaps spanning multiple year levels
- Your child has lost confidence and associates maths with failure
- You can’t pinpoint where the actual problem is (and neither can your child)
- Your child has been using the platform for months with no measurable improvement
That last point is the red flag I see most often. Parents tell me, “She’s been doing Khan Academy every night for six months and her results haven’t changed.” That’s not the platform failing — it’s the diagnosis step that was skipped.
What Does Structured Tutoring Do Differently?
The difference between an online platform and structured tutoring isn’t just “a real person.” It’s the assessment-first approach.
At Spectrum, every student begins with a comprehensive assessment that maps their ability across multiple mathematical domains. We don’t ask what year level they’re in — we determine where they actually are. Then we place them in the appropriate band with students at a similar level, regardless of age.
A Year 4 student and a Year 6 student might sit in the same Water-band class because they’re working on the same foundational skills. Neither feels behind. Neither feels held back. The instruction meets them exactly where they are.
We then track progress weekly — not through gamified dashboards, but through actual performance data on curriculum-aligned tasks. Parents receive regular reports showing measurable growth. Our students average 15–20% improvement in assessed performance after one term.
This isn’t because our teachers are magic. It’s because teaching the right content at the right level produces faster results than practising the wrong content at the wrong level — no matter how good the algorithm.
The Real Question Parents Should Ask
Before spending another month on Khan Academy or renewing that IXL subscription, ask yourself one question: Do I actually know where my child’s maths gaps are?
If the answer is yes — and the gaps are small — online platforms are a great, affordable way to close them.
If the answer is no — and you’ve been hoping the platform would figure it out — it’s time for a proper diagnosis.
Our free online assessment takes 20 minutes and gives you a clear picture of where your child sits across key mathematical domains. No commitment, no sales pitch. Just data.
Because the goal isn’t more screen time. It’s knowing exactly what your child needs — and then giving them exactly that.
How to Get Started
- Take the free assessment at spectrumtuition.com/online-assessment — 20 minutes, done from home
- Review the results with our education team — we’ll show you where the gaps are and what they mean
- Decide your approach — if the gaps are small, we’ll tell you which online platform to use and what topics to target. If they’re deeper, we’ll recommend a structured program at one of our 15 Melbourne campuses or online.
The worst outcome isn’t choosing the wrong platform. It’s spending months on any platform without knowing whether it’s actually helping. Start with the diagnosis. Everything else follows.
