About Dyscalculia

Recommended Links

Dyscalculia is a term for specific learning disabilities in mathematical ability affecting up to 6% of children (US figure).

The disorder can manifest itself in many ways including difficulty in understanding numerals, problems with visual and symbolic representation, inability to carry out specific types of mathematical operations or difficulties with fundamental spatial and numeric concepts.

Primary Dyscalculia is thought to relate to problems in working memory and the inability to relate numbers as abstracts to absolute quantities. Learners with Primary Dyscalculia may be assisted using visual/spatial cues and strategies, though for many basic concepts of number and arithmetic will never be straight forward.

Spatial Dyscalculia, sometimes known as non-verbal learning disorder, is rarer than Primary Dyscalculia and centres on the inabilities to visualise mathematical concepts and process mathematical and other representations.

Although around half of dyslexic pupils are thought to have no unusual difficulties with regard to mathematics, and where they do dyslexia alone could account for them, it is considered likely that more individuals diagnosed with dyslexia are affected by dyscalculia than the general population.
