I'm wondering what is "normal" in terms of student-teacher ratio for elementary school, particularly 3rd grade. If we accelerate DS for math, he would be in a class of 32-33 kids vs. 22-23 if he stays in the grade for his age (2nd grade). The class of 32-33 kids wouldn't be a huge problem, except for the fact that the work is still going to be too easy. So I'm guessing with a class that size it would be unreasonable to expect the teacher to differentiate the work for DS and teach him at his level? But more reasonable with a class of 22?

Has anyone dealt with class sizes this large in elem school? I am really disgusted. I'm not sure how they would even fit the kids into the small classrooms. It would be like a herd of cattle fenced in.
