I just got my keys to my new classroom last week and noticed there is not a lot of room for bulletin boards and wall space to hang stuff. One whole side of the room is gone because of windows and the other side is gone because of sheleves. That leaves me with 1 white board, 1 chalkboard and 3 bulletin boards. Im trying to decide what I should hang up because I realize i need to limit myself now. What are the must haves that I should have posted in my first grade classroom?
