How do you keep all those points up when kids are turning in extra credit at random times? Use extra credit tickets! I developed this idea about 4 years into my career and it has been a Godsend... When a child turns in extra credit (I usually assign specific assignments/projects up to a specific amount of points due on a specific date), they earn a particular amount of points, and then I write them a ticket. They have to KEEP the ticket SAFE and then turn it in when they want to improve their grade. If the ticket is lost, the points are too (teaches responsibility). It also has an option for the ticket to expire at the end of a designated quarter (you decide).
