Pinner says "Each classroom decides on a theme and then the students create poetry about the theme. These make an adorable display for April (it is poetry month, I think). To go hand in hand with the project, we compile all of the student poems into a school-wide anthology and give a copy of the anthology to each child! They LOVE it! They read those anthologies cover to cover!"
My interactive bulletin board for the "Sailing for Treasure" school wide theme. We have one artist for each month we are in school. Aug/Sept and Dec/Jan are combined. One piece is featured from each artist. The students will fill out which piece they think was created by the current artist of the month. I will draw from the correct answers and that student will earn a piece of candy.
Racecar theme with students from one class "competing" against another in the hallway. One suggestion -- to follow AR best practice, make the "pit stops" 10%, 20%, 30% (etc.) progress toward their goal instead of 5, 10, 15 (etc.) point levels.
