It seems like a good place to start would be to work on Memorization in general, perhaps touch typing to start since it's so useful, then some quotes and poems, then back around to math facts. Here's a post about Automaticity
http://wp.me/p2tcDf-1SSo my idea is that she work on the general topic of Memorization first, then concentrate on Math Facts in particular, then use a program like Aleks.com to fill in the details. Sites that teach 'Mental Math' might also be helpful. How is she with counting? How is her spelling? Can she associate numbers with letters, emotions or physical actions to
The Eidie book, Dyslexic Advantage might give some insights as well, but I haven't gotten far enough in to it to say for sure. I hope someone shows up with specific help for Math Disorder soon. They talk about the square law as a rule of thumb 'it takes the square root longer to learn something if you're dyslexic than if you aren't. In other words, if it took four hours to learn something for a nondyslexic, it would take twice as long for a dyslexic; if it took one hundred hours it would take ten time as long.
((note that the Eidie's use the term dyslexia very broadly to cover problems with procedural memory, working memory, handwriting, learning by observing, rote math, visual and auditory function. They also identify them as having strengths which are due to their cognitive differences, which they call: Material reasoning, Interconnected reasoning, Narrative reasoning, and Dynamic reasoning.))
