Dyscalculia is a condition that affects the ability to acquire Mathematical skills. Dyscalculia learners may have difficulty understanding simple number concepts, lack an intuitive grasp of numbers, and have problems learning number facts and procedures.
Even if they produce a correct answer or use a correct method, they may do so mechanically and without confidence.
Dyscalculia is a heterogenic condition which affects 3-6% of the population.
Karagiannakis and Cooreman (2015) proposed a classification model of mathematical learning difficulties as:
- Core number - difficulties in the basis sense of numerosity and subitising.
- Visual-spatial – difficulties in interpreting and using spatial organisation and representation of mathematical objects
- Memory – Difficulties in retrieving numerical facts and performing mental calculations accurately
- Reasoning – difficulties in grasping mathematical concepts, ideas and relations and understanding multiple steps in complex procedures
