You sound like you have some great ideas right there!! The younger grades can draw the new center and maybe the older grades can make a collage from the picuters that were taken. Or many craft stores offer already cut mats that are great for mounting many pictures (I did this with the construction of our new home). The older students could also help mount the pictures done by the lower grades on inexpencive tag/poster board. You had some wonderful ideas and I've just given myself a few! (We are building a new school and you have helped me turn on a lightupstair!)
I am in charge of decorating for the elementary schools ribbon cutting of the Environmental Center. Everyone that helped with the Environmental Center is coming. It is held in the library. ANYONE HAVE ANY DECORATING IDEAS. The food has already been determined, just need decorating ideas. Maybe something the children can make, pictures of the Environmental Center progress? I don't know and need your help.
