Do Now: Be a dick and give a review quiz today to the five students whose parents aren’t keeping them at home and are sitting in your class right now. It might be Halloween to some, a day of pranks to others, and gang initiation to even fewer. But to normal citizens, it’s a Friday, and people work on Friday. So give them work. If they complain, explain that you’re in costume as the scariest thing they can imagine: a demanding, strict teacher. And remember, as you’re handing out the scantrons, be sure to say, “Trick or Treat!” They’ll remember that one later for sure as they eat their Tootsie pops and candy corn.
