I have taught 4th grade for 7 years now and 6th grade (at an elementary level) for 2 years. I use the license system. I print a license every week for every child with their name and the date on the top (with a picture of our class mascot a fish) and then I print Monday - Friday down the center. The notecards are up and down, and I have created a template for them using word. The students all have a library pocket taped to their desks along with their nametag and the license stays in this pocket. For discipline problems I punch a hole in the license. At the end of the week I collect them and if they have gotten less than 2 punches for the week they eat in the classroom on Monday, but I like the idea of being able to bring a snack or drink etc. as well. We also have what we call Fun Friday and if they have received less than 4 punches they get to join an activity on Friday while the others have enrichment work to do. For the most part the students who miss Fun Friday are the ones who need enrichment work!!!
