There is a large number of 8th graders who are too immature to pick an appropriate nick-name. It is enough of a nuissance that I prefer to play review games that have a name gernerating feature.
You can create a “class list” that they have to pick from. I had to do that with two of my classes.
You can just put “Bob” and they all have to choose that one name and have NO idea who is on their team b/c everyone is Bob! 🤣
