I came up with this idea when I was working with a very challenging student with Autism. This is a great visual behavior tool to give your students. Use these to remind students of the options that they have before they "blow up." I also incorporated the use of the keys into their behavior goal. It helps with getting kids to recognize the choices they have when they need a break or time out. Anytime you work with students that are behaviorally challenging, you want to take a proactive approach. These keys will help you accomplish that!
The keys are editable so you can customize them to best suit your needs.
