Dyscalculia

Dyscalculia is a specific learning difficulty in mathematics. Like dyslexia, dyscalculia can be caused by a visual perceptual deficit. Dyscalculia refers specifically to the inability to perform operations in maths or arithmetic. It is a lesser known disability, much like Dyslexia. In fact, it is considered a variation of Dyslexia. People with dyscalculia generally have a normal IQ level, but have problems with mathematics, time, directions etc. Many people with dyscalculia have higher than normal IQ scores. Dyscalculia is not rare. The prevalence of dyscalculia ranges from 5-7 percent of the population. 15 percent of those with dyslexia have dyscalculia as well.

Potential symptoms

Frequent difficulties with numbers, confusing the signs: +, -, / and x, reversing or transposing numbers etc.
Difficulty with time-tables, mental arithmetic, directions etc.
Good in subjects like science and geometry until a higher level requiring maths is needed.
Difficulty with the abstract concepts of time and direction, often with the concepts of 'left' and 'right'.
Difficulty with everyday tasks like making change, calculating tips, and reading analog clocks.
Inability to do financial planning or budgeting.
Inability to grasp and remember math concepts, rules, formulae, sequences.
Difficulty keeping score during games.

Dealing with students having dyscalculia

Encourage students to "visualize" mathematics problems and give them enough time for the same.
Have the student read problems out loud and listen very carefully. Often, the problems arise because a person discalculia misunderstands the mathematical problems.
Provide examples and try to relate problems to real-life situations.
Provide uncluttered worksheets.
Discalculia students must spend extra time memorizing mathematics facts. Repetition is very important. Use rhythm or music to help memorize.
Allow the student to take the exam on a one-to-one basis in the teacher's presence.
Don't scold or pity the student. Behave with him/her like you do with anyone else.
