I have a monkey theme in my room, but you can put it with any theme.
My board says "We're Bananas About Books."
I have banana cut outs and I started with one or two of my favorite books. I write the Title, Author and my name on the Banana and staple it to the board. When the kids come in, I tell them that on their own time, they may go to the BB one at a time to fill out a banana. Last year, my board was full. They loved it,and it never cause any problems with traffic or behavior.
