I use these in class to make sure students are participating. Any time a student does something good, follows instructions, or answers a question in class, they get a 2 point ticket. At the end of each quarter, students turn in their 2 point tickets as part of their grade. (For example, every quarter they need 10 points work of 2 point ticket, so they need to turn in 5 for full credit.) I print them on different colored paper for each quarter.
