We try to keep it silly. I have 9th and 11th grade English. We can't do the serious ones like detention if an event just made them fall in battle.
I usually divide this with RGs and a fun quick D20 thing for them to do to get them used to using the Discussion panel since that comes up later. https://game.classcraft.com/import/quest/PZGb8t3N...
New Roles Suggestion
My students and I will brainstorm at the end of each semester on how I can be a better teacher, and we usually drift to Classcraft since it plays such a dominant role in their memories of my class....
