I think the class size is too big -- she can't give proper attention to each child. I am not the only parent who thinks so. What should we do?
Keep in mind that there is a big jump between second and third grades, both in curriculum and in teacher expectations. Many third-grade teachers believe that the children need to know they are no longer in primary school, and that more will be expected of them both academically and behaviorally.
It sounds like your son's teacher has had a tough situation this year. Even with an assistant, 35 children is an incredible number to teach. Current research has shown that children's achievement improves tremendously when class sizes are reduced. With that many children, it's no wonder that the students have trouble listening and paying attention. Talking with the principal may also improve that situation for next year as well.
