At the beginning of each school year, you'll find them posted in your child's class if he goes to school. I have to say the classroom "rules" are much more child-friendly than they were in the past. In the past? You just had better obey the teacher at all times and be a good kid. "Good kid" is undefined.
Now, the rules are at least nominally much kinder. Sometimes teachers have the children suggest rules for the class. Which is a joke but it does help give the appearance of "buy-in." It would be fun if an entire class demanded that they got to eat their own lunches on the playground each day and that school now ends at 1 pm. Or if they were smart enough to declare that they did not want ANY rules, thankyouverymuch. I'd be just the sort of kid who would ask for this stuff and find no one would back me up. :/
Woodjie goes to a school with a shark mascot. So everyone's classroom rules are already laid out. Sharks are Safe and so on down the acronym. Every morning when Woodjie gets up he asks, "I are being a (schoolname) shark?" Yes! You are going to school today. He has a really awesome teacher and I'm enjoying his going and learning. (It's next year I worry about when all those supports are gone.)
Does your school/class have a list of "rules?" And if you're a homeschooler, do you even bother with them? I'm sure I have a bunch of rules, but they're not written down. Emperor is in a very good habit of going to do his schoolwork right away every weekday morning.
