Students Test Me

I have two students that continue to test me and what the consequences will be. I have discussed their behavior with them one on one when we are both calm. We have thought of solutions together. The students have chosen their choice of solution. It would work for a few minutes and then back at it again. Interesting enough a solution has been offered that consists of asking the student to stop. They choose this one and within a few minutes are doing the behaviors again. When we go back to the drawing board and discuss what’s been happening, I ask them to choose a new solution since that on hasn’t been working. They choose going to the time out table, then when they begin to exhibit the behaviors, I feel like I am punishing them by asking them to follow through with there chosen consequence.

Any Suggestions?
