2. Instructions for using this template. Remember this is Jeopardy, so where I have written “ Answer ” this is the prompt the students will see, and where I have “ Question ” should be the student ’ s response. To enter your questions and answers, click once on the text on the slide, then highlight and just type over what ’ s there to replace it. If you hit Delete or Backspace, it sometimes makes the text box disappear. When clicking on the slide to move to the next appropriate slide, be sure you see the hand, not the arrow. (If you put your cursor over a text box, it will be an arrow and WILL NOT take you to the right location.)
