Pemberley, how frustrating! Feeling helpless to provide the support/ remediation your child needs is just the most awful place. You've achieved so much already though, so I know you will find your way around this seeming dead-end, too. Your daughter is a truly amazing child, and I have no doubt she will ultimately find some extraordinarily creative way to do these tasks.

It sounds like aeh has pointed to a useful resource. I'll add the math part of the Yale dyslexia site, just in case you haven't seen it: http://dyslexia.yale.edu/math.html The videos at the bottom of the page provide some interesting examples of approaches you could take if you haven't already tried them (though I can't speak to effectiveness). This may be the same/ similar to the TouchMath aeh is suggesting?
