I use this punch card in my classroom as a little reward and incentive when students score a 100% on an AR test or KidBiz quiz. They receive one punch for each 100. It's a nice and easy way to acknowledge smaller and more frequent achievements, while it also encourages them to put forth quality work and effort. When they've earned 20 punches, students can pick from any number of rewards or privileges. I print the cards out on colored cardstock and use decorative punches in different shapes.
