Using incentives for positive behavior is a wonderful way to motivate students to do the right thing. This is the chart I use in my classroom to reward the entire class for positive behavior. The students earn a new app by exceeding “apps-pectations”, getting compliments for great behavior from other teachers, hard work by all students, etc. When the iPad is full of apps the class gets free choice iPad time.
I have both my iPad and apps lamented. After attaching magnets to the back of the apps, they are very easy to put up on my whiteboard.
