anonymous student names/ no dirty words#248

I make a class with Spanish animal names or Spanish people names to pick from. It is a way to teach content that is not in the book. It also makes them not focus on the board so much. The problem is that many of them pick the same name at the same time and I have to kick them out and keep trying to sign in as someone not picked. I know the easy answer is to assign names, but then it would not be anonymous anymore.
