4. Setting up Teams I will put you in teams of 4 or less. Now that we have teams, each team will choose one person to be the team leader. This person will be in charge of materials, and they will answer the questions for the team. Team leaders need to go to the back square table and get one white board and one marker. I also need one very responsible person on each team to record the score and lifelines for their team. You are the team recorders. The recorders will keep track of lifelines. Each team has one 50:50, one “call-out”, and one “Teacher-help” during each game

5. During the game: everyone will figure out the answer to each question. The team leader will have to confer with the group members to decide on the right answer The team leader will write your final answer on the dry erase board and hold it up for me to see. Work together to find the right answer! Help teammates who are struggling! Because of how the guided notes are structured, you can’t work ahead.

We will start with the $100 dollar question. If your team gets it correct, you will earn that dollar amount in the game. For question 2, if your team gets that correct, your team would have a total of 300 points. If they don’t get it right, you would be wiped out to 0 dollars. Then, for question 3, you could still earn the $300 if your team gets it correct, but you wouldn’t have the scores from the first two problems any more. Questions?
