Thanks to Mark for his post. As parent of a dyslexic child, I've found out firsthand how much misinformation there is about dyslexia - I've had to wade through gobs and gobs of it. A lot of bunkum being sold as dyslexia cures, too, and a lot of money charged for it. Best book I've read on the subject is the one by Sally Shaywitz, M.D., called Overcoming Dyslexia.   BTW, Liz, I think term for what you describe is dyscalculia.
