What is dyscalculia? Dyscalculia is a complete inability to acquire an intuitive grasp of number concepts (e.g., intuitively - and visually - counting five small items, placed next to each other, at a glance) and basic numerical skills, in terms of numerical relationships.
Dyscalculia adversely affects the ability to understand quantitative and spatial information, number facts and procedures (e.g., estimating sizes / dimensions and keeping track of time). Those with dyscalculia are likely to find it difficult to manage daily activities, such as dealing with money and sticking to a time schedule (Hulme et al., 2009: 184). Estimates indicate that about 3% of people are affected.
On the other hand, maths anxiety is caused by a feeling of tension and apprehension, likely to be due to a combination of factors such as prior bad math experiences, imposing authority figures and/or having to work our maths under time pressure. Previous negative experiences may, for instance, have led to a perceived risk of public embarrassment when working out fractions, percentages and averages and, indirectly, to money issues. Anxiety can interfere with maths performance ability, in terms of the manipulation of numbers and the solving of mathematical problems, in a wide variety of ordinary life and academic situations. However, maths anxiety is not dyscalculia.
