I nstructions for Playing Jeopardy: · Edit the category titles, questions, and answers. Hide the answer text behind the yellow box. If you click the yellow box, it will fade away - don't worry. It will reset when you come back to the page. If you would like to add a "Daily Double" question, choose the square from the game board that you would like to be the DD and change the link to the Daily Double slide. Divide your class into four teams (or whatever works for you. Just edit the Scoreboard slide appropriately). One representative from the first team chooses a category and a question value. Click the yellow value to go to the question. · Read the question aloud. (You can play the Jeopardy music by clicking the "Music" link at the bottom of the slide if you wish. Click it again to stop it.) When the correct answer has been given, reveal the answer by clicking the yellow- edged box. (You might have to click twice.) Then click "Score" to go to the Scoreboard. Note: Using the left and right arrows will not navigate the game properly. Use only the links that are contained within each page to get around. · Use the pen to add the team's scores. Then click "Back" to go back to the Game Board. · Before going on to the next question, drag the small blue box that is located directly below the Game Board over the last question used to remove it from play. It is cloned infinitely so just keep on draggin'! · When students find the Daily Double slide, click the image to move to the wager screen. Only the team who chose the question may answer. One representative from the team can use the pen to write their wager in the box. If the team answers correctly, they add their wager to their score. If they answer incorrectly, the wager is deducted from their score.
