My school bulletin board for the month. We wrote "I Wish" poems then took pictures like we were blowing a dandelion. We cut them out and pasted them next to a dandelion that we made out of yarn and sticks.
Checkout this great post on Bulletin Board Ideas! - make pictures of your students' faces at the beginning of the year, print out, mat on cardstock, laminate, and use in various decorations throughout the year.
