This is a punch card I created to reward students for completing homework assignments accurately and on time. With each completed homework assignment that I check from them, I use a specially shaped hole punch (not a plain round punch that they could do themselves) to punch their card in the next spot. At each corner they earn a different reward (small candy, extra credit, big candy, a free homework pass). When they finish a card, they get to start over! There's no limit to the number of cards they can go through in a year.
