Here is a behavior management tool that will allow students to reflect on their poor choices. When the student has to be redirected for an unfavorable behavior, he/she can take a moment to "think" about what caused them to receive this attention from the teacher.
Instead of sitting isolated doing nothing, I like to keep this on a clipboard at a "special desk" where the student can fill out this form and reflect on how he/she will make better choices next time.
This can also be sent home for a parent signature, which should discourage the initial unfavorable behavior.
Thank you for your interest.
