                  Practice!
 Try the rest of the practice with your team.
 The team who works the best today in
  class will have their homework assignment
  cut in half!
 I am looking for teams who:
     …work together well (no one rushes ahead
      and no one falls behind).
     …help each other.
     …stay focused on their assignment.
