Since peaceful coexistence usually requires some rules, "Heart Education with Oups" also has classroom rules. You can find them here for download. Enjoy!
By the way: If you don't want to miss anything from Oups, visit our "Heart Education with Oups" group on Facebook
Oups completely refrains from prohibitions in his rules, so all rules are very positively formulated.
Two more tips from me:
I think it's great when the classroom rules are introduced together with Oups and the children based on current events. Children often want certain rules of conduct and then formulate them themselves.
I always make sure to introduce only those rules that the children really need. The world of children is already full of prohibitions and commands.
