I originally made this for my speech therapy kiddos. They LOVED the iPad and would work hard for "chips" to place on their stars to earn reward time. You can laminate it and either give them chips or just use a dry-erase marker to mark them off as they complete a trial. I made a page with 5 and 10 stars as well as one with a blank reward that you can put whatever else you want in.
Hope you find this useful as I did!
