I do this with students in my attendance matters small group (difficult time with attending school) as an incentive or motivation to get the students to school on time and just to get them to school.
We meet every Friday for 20-30 minutes and do activities. They also get to put a sticker in each box for each day that they attended school for that particular week. Students get excited every Friday for this part!
I keep the half sheet with me so they students don't have to keep track of it.
