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. Dyscalculia is rare and many cases are mis-diagnoses of normal Dyslexia, which also makes learning mathematics difficult.

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 normal people.
