I use this with a student who is not organized. Every week or how often you would like, take out the mystery check. Tell your student you are doing a mystery check and ask them what they would like to earn for the check. If they meet your passing criteria, they get to earn the prize, activity, etc. of their choice! If not, they need to correct their mistakes. Also a great way to progress monitor organization skills... keep copies of the mystery check and see how they have improved over time. This is a word document so customize it how you like!
