Unit 2: ExpressionsTeam recorders, keep track of the 3 lifelines
you have for this game. 6Setting up TeamsI 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
gameDuring 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 answerThe 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 cant
work ahead.

scores The team recorder will keep track of each problem. 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 dont 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 wouldnt have the scores from the
first two problems any more. Questions?Unit 2 - Expressions$50,000
