I have Fred Jones's book and have been reading it plus developing my own idea for using Preferred Activity Time with my Individual Studies class. (It is a class where my special education students can get homework help, read, and I usually review a little bit from their pre-algebra classes.) Can you explain how you use Preferred Activity Time in your classes? Do you have points for daily, weekly, monthly, or longer durations for rewards? What are the rewards at the different amounts of points? What rewards do you find work well? I am considering daily rewards (or even more often throughout the class) for points because my students have difficulty at times staying on task for the entire class period. Thank you for any advice.
