  1. Geopardy Margarita Perez Texas Woman’s University MATH 4313 mago0789@yahoo.com

  2. 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.
