What’s in it

Symptoms

  • Difficulty understanding number concepts and arithmetic.
  • Trouble telling time, counting change or estimating quantities.
  • High anxiety when faced with mathematical tasks.

Age & Gender

  • Signs appear early, often when learning to count or recognise numbers.
  • Research suggests it affects males and females equally.

Misconceptions

  • It’s not just being 'bad at maths' or lacking effort.
  • It’s a neurological difference, not a sign of low intelligence.
  • It’s not rare, just less frequently diagnosed than dyslexia.

Diagnosis

  • Assessment by a specialist teacher or Educational Psychologist.
  • Standardised tests measure number sense and calculation ability against age norms.

Support options

  • Multisensory teaching using physical objects like counters.
  • Technological aids like calculators or voice-activated apps.
  • Focus on practical maths needed for daily life (e.g. money, time).

Support

  • Provide reference charts or visual aids for numbers.
  • Allow extra time for any task involving data or figures.
  • Avoid putting them on the spot with mental maths questions.
