She is NOT a naughty pants! You know that.
Hurray for the teacher making her calendar helper. Great idea!
If it were me, I'd talk with her and say something like "I know how excited you are about school and I'm excited for you too. I loved school and learning and being around classmates and making friends. Gosh, this is such a fun time in your life. Ms. So and So made you the calendar helper because she recognized how enthusiastic you are about school. She knew you would be a perfect choice for helping her with the class. We've talked before about how you can only talk when the green paper is on the desk. And, you know the teacher has to have that rule so that the whole class can learn, right? You know she isn't doing that to be bossy or or anything like that, right?
Some of the other kids may not know that. So, since you are such a great helper and do understand the rules and why theteacher has to have them, I was wondering if you could help Ms. So and So by SHOWING the other kids how to follow the rules about the green paper and red paper. Could you do that for Ms. So and So? I think she would be very happy to have your help with this.
