I'd be more concerned about the message he gets from having work that doesn't teach him anything. In preschool, it shouldn't be about academics. There should be plenty of nature, pretend play, exploration for learning. Pencil/crayon work should be a very small part of it at most. And during that time, I'd expect the teacher to be giving him something decent to work on. Just a worksheet of more advanced concepts, like rhyming words or whatever is appropriate.
This is complicated somewhat by the fact that I live in a universal preschool state. By law, all children in free preschool (which he is) must receive a certain curriculum, so he has to do all this stuff--letters, counting, writing his name. This doesn't take the whole day, but it takes some time every day.
But preschool is almost over anyway. What I'm wondering is whether or not to point next year's K teacher in this direction.
