Before school starts, I put up a 3-D paper tree by bunching up colored butcher paper and stapling it onto a blue background. The tree begins the year with apples. I put the students' names on them and write 'pick of the bunch' on a paper barrel. I create a pilgrim scene beneath the tree in November. In December, it becomes a Giving Tree when we put food for the needy beneath it and in the spring we plant tissue paper flowers below it. Other ideas come to mind as we go through the curriculum. My students enjoy creating the changes and sometimes come up with new ideas too.
