He's accelerated to 1st for math, but in K for reading? Is there less writing involved in math?

DSs situation was very similar when he began K...he went to 1st for reading, but the writing didn't seem to factor in (and DS has always had poor handwriting). Granted, the 1st grade teacher (who ended up having my DS in her class the next year) always commented on DSs writing and how it needed improvement, but it wasn't a requirement for his accelerated reading instruction.

I think I would have been upset if he'd been pulled back solely based on his underdeveloped writing ability and I might have questioned it.
