i used these three boards to out up examples of the students' projects. it helps me remember what grade is doing what, lol. i keep confusing 3rd and 4th grade and 1st and 2nd.
i also organized all of the materials for each lesson into these bins. everything is cut and labeled. the folders underneath have handouts etc., the lesson plan, and whichever of my sweet elements and principles posters i need for that lesson.
it's all pretty much designed so that anyone can come in and teach my lessons in case i get sick or something.
