These are Class Bucks that I use in my classroom. There are $1, $5, $10, $20, $50, and $100. We exchange them to practice for real money! Print them out on different colored paper and laminate them. The students love being able to earn money for homework, following procedures, helping others, etc. These are a GREAT way for positive reinforcement, especially outside of the classroom and in transition areas (hallways, bathrooms, etc).
If you would like for me to add your name to the Class Bucks to ensure they are returned to you if lost, please leave me feedback and/or message me with your name and I can make those for you. I have my name on my Class Bucks b/c students will forget them and leave them places. This way they are always returned to me and it saves me having to make more every year.
