Owl Job Chart I made for my classroom. Besides the owls (that I purchased), the whole thing is colored butcher paper or a boarder. I punched a hole in my owls, and put straight pins in the bulletin board. It makes rotating the owls really easy. The Carpet Cleaners at the bottom are the rest of my students. Each week when I switch them, I will put them on the back of the pile and restock the tree from the front.
