I looked at a few of the ones people post and how they made them and I was FINALLY able to make one of my own, so here it is! Thanks for all the ideas. I'm thinking of using the AR one as well this next year!
I used my punch card for homework. If student return his/her homework, he/she would get a punch. In the morning, students would place homework and the punch card on their desk. I walked around, glanced at homework and would punch the cards. When a student filled up a card, he/she would pick from the treasure box. The district I worked in had required math homework each night. If a student returned all the homework he/she picked for the treasure box about every 2 weeks. This worked well for the students and me.
I'm going to use mine as an added accountability factor during our work station time. I typed out new rules for this time that go along with our schoolwide PRIDE expectations (preparation, respect, integrity, discipline, and excellence) and what each of those things mean during work station time. When the kids complete their "must do" task and show they are following the rules, I will give them a punch at the end of our work station time. When they get 20 punches on their card they'll get to choose something out of the prize box.
