How to play JEOPARDY!

The class will be split into two teams, the RED team and the GREEN team.

When a question is displayed, the RED team will use the ABCD keys on their clickers to answer. The GREEN team will use the EFGH keys to answer.

The team with the HIGHEST PERCENTAGE of correct responses will earn the points for that question, AND the right to pick the next category!

Setup Instructions.rtf

Thanks for downloading my new Jeopardy Template using the Smart Response System! Here are some instructions to help you set up your game board and play the game with your students. SETTING UP THE GAME BOARDOn the opening screen, insert the subject of your Jeopardy game. Review the Instructions slide and make changes so your students will understand how to play. You can also change the Sample question if you want to… but why would you??? On the Game Board, edit the category titles. Question slides have been organized into Groups to help you navigate more easily. For each question slide, add your question text and four answer options. Hide the correct 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.  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. PLAYING THE GAME Divide your class into two teams, Red and Green. Have students sign on to the Response clickers anonymously or using their ID’s – the game will work either way.  Open the Response tab in your Toolbar, and keep it open throughout the entire game. Go over the Instructions slide with students so they understand how the game will be played.  Guide students through answering the sample question.oRead the question aloudoThen in the Response tab, select the “Progress” button and click “Start this Question.” After all students have answered, stop the question. oReveal the correct answer by clicking the yellow box; it will fade away. oLook in the Response tab to see which team had the highest percentage of students choosing the correct answer.oClick “Go on to the Game Board” One representative from the first team chooses a category and a question value. Click the yellow value to go to the question. Follow the same steps above to answer the question. Click “Score” to go to the Score Board and use the pen to keep a running total.  Return to the Game Board and drag the small blue box that is located directly below the Game Board over the last question to remove it from play. The team who answered the last question gets to choose the next category.
