Who Wants to Be a Millionaire?!
Goal: Reach $1,000,000
• 4 teams of 7-8 students  This is your “audience” when
you use a life-line.
• Each person on each team will answer the given question
individually.
• If you are stuck, you can use a life-line. Each team gets 4
life-lines:
• 2 “phone a friend”  choose someone on your team to
bail you out
• 2 “ask the audience”  discuss with your entire team
the correct answer
•Each Q you answer correctly, you
earn a level on the board.
•If you answer incorrectly, you move
down a level on the board.
•Goal is to reach $1,000,000
