For us, loss of screen time for a month might be a lot or too much.
Recently, my 7th grader and his friend got detention for talking excessively in their accelerated math class. (It's Algebra I, although it's called some other weird name since it's common Core). I was like, really??? Who gets detention in Honors Math?
I had him write a long letter of apology to the math teacher- he hated doing it and hated giving it to the teacher but I think he got the message since he doesn't want to do that every day.
We explained to him that there are like 30 kids in the class and the teacher has probably 5 periods a day or 150 kids! The teacher doesnt' need some kid to be a pill. Who needs that?
I would say two weeks but spouse is insistent on a month. Also is a lot more convinced our kid is incorrigible. DS will write the apology letter, after reading the note we got from the teacher. He will also likely get to write "I will respect my teachers" several times.
