Do these kids just not have parents? Are teachers unable to get parents to require their kids leave their phones at home? When I was in high school we had Nokia phones that did basically nothing but calls and snake.
I recommend no one be a teacher in the US. It’s mostly daycare for those who can’t homeschool or private school, for whatever reason.

(Search “parents” in r/teachers on Reddit for more, being a teacher in the US is a shit show; I have helped more than one teacher switch careers to save them from public education)
Administrators are no better. They change policies year to year, more paperwork, more training needed, more rules. A lot of them have never been a teacher even.
