Heart tree- Give love- use sticky heart stickers . -could make as a bulletin board and students write ways to show love/care on the hearts (good idea for valentines day, can send it home after too!) good idea for the school store.
New Years Idea: Start the year with an empty jar and fill it with notes about good things that happen. Then, on New Years Eve, empty it and see what awesome stuff happened that year. Good way to keep things in perspective.
