Today is Dyscalculia Day (3rd March, or 3/3), chosen because many children with dyscalculia struggle to tell the difference between 3 and 3 when written side by side.
If your child works hard at maths but still can't remember basic facts, struggles to count money, or panics when they see numbers, this might be why.
Dyscalculia is a specific learning difficulty that affects understanding and working with numbers. It's not about intelligence. Children with dyscalculia are just as capable as their peers. Their brains simply process numerical information differently.
According to the British Dyslexia Association, dyscalculia is "a specific and persistent difficulty in understanding numbers which can lead to a diverse range of difficulties with mathematics."
Research shows that 3-6% of the population has dyscalculia. That's roughly one or two children in every classroom. Many go undiagnosed for years because they're told they're "just not a maths person" or need to "try harder."
All children find some maths topics difficult. Dyscalculia is different.
Children who find maths hard usually improve with practice and good teaching. Children with dyscalculia have persistent difficulties despite effort, quality teaching, and intelligence.
The core problem is weak "number sense." This means they don't have an intuitive grasp of what numbers mean or represent. Looking at two groups of objects and knowing which has more without counting feels impossible. The number 7 doesn't automatically mean "this much" in their mind.
Common symptoms include:
Early years (Reception to Year 2):
Years 3-6:
The key indicator: Maths achievement lags significantly behind other subjects. Your child reads well, writes well, but maths feels impossible.
Your child goes to buy a comic that costs £3. They have a £5 note. They can't work out how much change they'll get, even though they can do 5 minus 3 on paper. Translating real-life into maths feels impossible.
At home, you ask them to set the table for 4 people. They can't picture what "4 forks" looks like as a group. They count them out one by one, unsure if they have the right amount.
In class, they learn their 3 times table on Monday. By Wednesday, it's completely gone. They have to relearn it from scratch. This isn't laziness. Their brain doesn't retain numerical facts the way other children's brains do.
Dyscalculia is neurological. It's linked to differences in brain areas responsible for number processing, particularly the left parietal sulcus and frontal lobe.
It often runs in families. If you struggled with maths, there's a higher chance your child will too.
What doesn't cause dyscalculia:
Dyscalculia rarely appears alone. Many children with dyscalculia also have:
Around 40-50% of children with dyslexia also have dyscalculia. The two often overlap.
Dyscalculia is diagnosed by educational psychologists or specialist assessors, not by the NHS. It's an educational difficulty, not a medical condition.
The assessment typically includes:
Schools should provide SEN support if dyscalculia is suspected, even before formal diagnosis. This means extra help, different teaching methods, or small group support.
The good news: with the right support, children with dyscalculia can succeed in maths.
What works:
What doesn't work:
At Primary Tutor Project, our qualified teachers have experience supporting children with dyscalculia and other maths learning difficulties. One-to-one tuition means teaching is completely tailored to your child's specific needs, using concrete resources, visual methods, and systematic approaches that work at their pace.
We don't just teach maths content. We teach strategies that help children understand numbers despite dyscalculia. With individual attention, your child can work through concepts without pressure, ask questions freely, and build confidence through small successes. Every child can succeed in maths with the right support.
Research from the UK shows that poor mathematical ability has serious long-term consequences. Children with undiagnosed dyscalculia are more likely to:
Early identification and support changes these outcomes. Children who get help early can develop strategies that last a lifetime.
Talk to your child's teacher. Ask for:
Keep records of what you notice at home. Note patterns, not just one-off mistakes.
Get specialist support. Don't wait until they're "further behind." The earlier children get help, the better.
Dyscalculia is real, common, and nothing to do with intelligence or effort. If your child's maths struggles feel different from normal difficulty, trust your instinct.
On Dyscalculia Day, the message is simple: children with dyscalculia need understanding, not more pressure. They need teaching that matches how their brain works, not harder worksheets.
With the right support, every child with dyscalculia can develop confidence and competence in maths. They just need someone who understands how to teach them.
