Behavior Cards are a great way to manage your classroom without the whole group knowing. I like to give these throughout the day. With Superstar cards my students earn a prize. The Think About It cards, my students get a chance to think about how to fix their behavior and when they are ready they will return the card to me. That tells both of us that they are ready to fix the behavior. I use the Refocus cards for exactly that. My students will refocus if they get one of these.
I use the tracker chart each day. I just use purple (superstar), green (did good), yellow (think about it), and red (refocus) to fill in the squares. This shows me any behavior patterns that I need to worry about. I may also write down notes to remember why the student was on yellow or red. This is also a great tracker for RtI.
