As I’m taking attendance, I give a very short quiz reviewing old material or on last night's homework. When our local bowling alley went to automatic scorekeepers I got the idea of using their old overhead scoring sheets for this quiz. I randomly select 10 of the students' quizzes each day. If eight out of the 10 quizzes are all correct, I then draw out two more to see if they “pick up the spare.” I then keep score for them on one overhead bowling sheet, and they compete against my other classes. The winning class gets a little something extra just for them. I have found that more students review yesterday’s work right before class and have fewer tardy students. Students really enjoy it, and it works well with all levels.
