1. Jeopardy v2.0 This version includes a new macro that removes the questions (this makes it so the program will run appropriately regardless of your PowerPoint version). First: in order to use this program, you need to enable macros. To do this, go to the Tools menu, select Macros, and then select Security. You will be shown a screen with various levels of security. Choose the radio button next to Medium and click OK. Then, close this file and re-open it. When it opens, it will ask if you want to enable macros. Click on “Enable”. To use this, simply edit the names of the categories to fit what you need, and then enter your questions (and answers) on the appropriate slides. Once you’ve entered all the questions, run the show. You must hit the “Start Game” button on this page (it will make sure all the questions appear). Click on the question chosen and that slide will come up. Click again to start the timer. When the timer reaches 0, click again and the answer will pop up. When the question has been answered, click the word “Back” in the lower right hand corner to bring yourself back to the main page. Once there, click the name of the team that got it right and enter the point value of the question. The score will be updated! That’s it! Comments? Suggestions?

This is, of course, a free program, but if you happen to feel like rewarding hard work with a little money, feel free to PayPal some cash to ryan.mayers@gmail.com.ryan.mayers@gmail.com Start Game
