Just to let everyone know! I recently went to Lowe's and got a large sheet of laminate white board (board they used in showers) for $10.99. They cut if for me and I got 28 dry erase boards that were 1ft x 1ft. It's a lot cheaper than buying them in the stores @ 3 bucks a white board. For erasers you can use old clean socks, and you can get cheap dry erase markers at some dollar stores. Im going to use these all the time in my classroom!
