Thank you all. These replies are helpful. The more I think about this, I realize that I'm not sure what my goals are. Truthfully, what I want is to find some stories about children who had similar weaknesses but practiced twiddling their thumbs while reciting numbers at home and brought processing speed up to speed.

Barring that, yes, your suggestion to get her properly assessed is a good one, and I will follow through. I'm not sure why the school hasn't initiated this, knowing what they know, and that makes me nervous. (Am I making a mountain out of molehill? or am I opening a can of worms?) I have called an outside psychologist and will pursue further assessment independently. I will also check out the book you've suggested, inky.
