So what kinds of accommodations can you get for the handwriting being the wrong size for the math paper? We have the same issue. I suggested blowing up the math sheets on a copier but the teacher didn't say anything. Plus he doesn't always line up his numbers into columns. He doesn't even use spacing between words when he writes so how would he be able to line up small numbers.

I don't know what the solution is. He may NEVER have decent writing but he still will need to do math and math ability is probably his greatest strength. What happens if a kid does not have hands or they are paralyzed and can't write or type at all? They still need to learn math.
