What are the teaching methods for dyscalculics?

Children with dyscalculia are slower than the regular student in the process of solving and understanding mathematics.

Some good advice for teachers would be to give the students with the disability work that is to their mathematical level. Since they will need more time to complete exercises, just give them what they need: extra time (no pressure).

Another thing to do is to give them non-verbal, but written instructions. They are already having a hard time with numbers, don't complicate it more for them by making them memorize what they have to do.
