Why is my child so far behind at maths despite trying hard?
Your child does the homework. They go to extra help. They understand it in the moment and then it's gone the next day. Peers who seem to try less are moving ahead. The gap keeps growing. You are not imagining it and they are not being lazy.
What might be going on
Dyscalculia is a specific learning difference affecting how the brain processes numbers and mathematical concepts. It is as real and as neurological as dyslexia, and it has nothing to do with intelligence or effort. Children with dyscalculia may struggle to retain number facts, understand quantity and magnitude, tell time reliably, or manage mathematical sequences -- not because they aren't trying, but because their brain processes numerical information differently. Executive function difficulties also significantly affect maths performance -- the working memory demands of holding numbers while calculating, the sequencing demands of multi-step problems, and the planning demands of mathematical problem-solving all rely on executive function. A child with ADHD or executive function difficulties may understand mathematical concepts but consistently lose their place, forget steps, or run out of working memory mid-problem.
What this is not
This is not a motivation problem. Watching a child try hard and still fail repeatedly is genuinely distressing for both the child and the parent. The consistent gap between effort and outcome is itself the clue -- it tells you that something neurological is making maths harder than it should be.
What you can do
Understanding whether dyscalculia, executive function difficulties, or both are contributing is the first step. A formal assessment can identify the specific profile and open access to accommodations -- calculator use, modified expectations, extra time -- that reflect what your child actually knows. A screening is a good starting point.
The free WhyTheyThink screening covers dyscalculia, executive function difficulties, and 14 other profiles. Takes about 5 minutes.

What is dyscalculia?
Dyscalculia is a specific learning difference affecting numerical processing -- similar to how dyslexia affects language processing. It affects number sense, arithmetic fluency, time, money, and mathematical reasoning, and has nothing to do with intelligence.
Can a child have dyscalculia if they can do some maths?
Yes -- dyscalculia is not binary. Many children with dyscalculia can manage some mathematical tasks, particularly with significant effort, while struggling significantly with others. The pattern of difficulty matters more than total inability.
Should a child with dyscalculia be allowed to use a calculator?
Yes -- calculator use is a common and appropriate accommodation for children with dyscalculia. It allows them to demonstrate mathematical understanding without being blocked by the numerical processing difficulty.
