I have a pretty good sized open wall behind my large group area that I would like to make into an interactive bulletin board type area. This was our word wall but it kept getting pulled down and was really scrunched so I took it down. I cannot put up a bulletin board there and can only use sticky tac or those 3m type hangers on the wall so I am limited but would like some ideas of what to put up there. I thought about doing some sort of letter matching idea because I have several kids that could use this but don't know exactly what. Any ideas?
