Got extra time on your hands before your next transition time? It never fails that I would have some extra time to fill during the day. Maybe it was the 5 minutes before we went to lunch or the 10 minutes before dismissal. I needed something to do during that time. I was introduced to this game years ago at a PD offered by my district where a Ball State professor was presenting. I don't remember what she called it at the time, but I've always called it Draw 5 with my students.
