Hi! Thanks for your reply.
I teach Tech Ed so they need their chromebooks everyday I have them in class so it is easy to see when someone is not prepared with a charged chromebook. I did think of your idea but actually work the opposite direction. Start with everyone at 30 points (max they can get) and then reduce it by 1 each time they are not prepared. Easier to track since I won't have to touch each grade of each student each class.
The only thing this does not track is the date they weren't prepared...in case it gets challenged then there is date tracking. So, curious what others have to suggest.
Thanks!
Kevin
