Transcript of Divide the class into three groups and have each group choose one person who will answer questions...
How to Play• Divide the class into three groups and have each group choose one person who will answer
questions on behalf of the whole group. • Have each group take out scratch paper, pencil and a calculator (optional)• Choose one group to start the game by choosing a category and an amount. • Click on the link to read the question. The group whose captain raises his/her hand first
gets a chance to answer, but they must wait for you to finish reading the question. If they ring before, they cannot answer that particular question.
• If the first group answers incorrectly, allow the other groups to try.• Answers must be given in the form of “who/what is…?” and 20 seconds are given to
answer each question.• Add money amount for correct answers, and deduct corresponding amount for incorrect
answers. • Keep score for each group on the board/overhead or any medium of choice. • Click on the pink back button to go back to the category board and have the team that last
answered a question correctly choose the next category. • Repeat above procedures until all questions have been answered for the regular round and
for double Geopardy. • After all categories have been played, show the final Geopardy topic. Have each group
decide how much of their winnings they want to wager and write it on a piece of paper . Once they all decide, give them 45 seconds to answer the question and write it down.
• Have each group reveal their answer and compute the final score. • Have some type of prize/reward for the winning team, i.e. pizza party, free homework
pass, etc.
