I am a Sunday School teacher at a nearby church and one of my jobs is to update a bulletin board every once in a while. Bulletin boards are a great way to give information or showcase students' to both students and parents. In a classroom, especially with math, it may be hard to find ways to utilize a bulletin board to display students' work. One idea is to have them create math related crafts such as color by number pictures. However, you need to make them fun and creative to catch people's attention, otherwise no one will ever notice them. Here is a photo of the one I did today. This board was not in a math classroom, but you can get the idea of the design from this.
