DS7 has dysgraphia and his math teacher is trying out math sites to replace worksheets for his homework, to accommodate both E's. I'm delighted by this and thought I could help out by canvassing the wisdom of this board. I've read threads on various math programs, but I don't know how/if any of them would work as worksheet replacements. He's doing grade 3 & 4 work and could go higher. Suggestions?
