My son has ADHD (or so they say). I developed two programs in MS Excel, to help him learn basic arithmetic skills. They are free for use with LD/Special Needs children/students.
Download site: www.geocities.com/ldprograms/arithmetic101
Or, if you prefer, you can go the long way round:
http://www.multiplication.com/computer_games.htm
(Arithmetic101 and Arithmeteach101)
The above link will take you to the same download site.
My son’s records are (All correct):
20 tables questions - 1m 05s
10 long divisions (x into xxx) - 1m 46s
10 long multiplications (xxx X xx) 8m 25s
Again, the programs are free for special needs use.
