DNA TEST REVIEW

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
