I print these out on bright orange paper. To save on paper, I have two on one sheet of paper. You only need to cut the paper in half. My students have to fill these out when they don't turn in their homework. They have to sign it and get parent's and teacher's signatures. This creates a sense of ownership when they didn't do their homework. It has cut down on missing homework in my class because they don't like having to fill it out. They will fill it out during their fun time (recess, and etc.).
