Don’t forget how Jeopardy! Works—instead of questions, the
students are given answers and they get points for coming up with
the questions.
You can edit this template by typing in the boxes, but you can only
run the game in Slide Show view.
The game board slide is linked to all the other slides in the
presentation. When you click a point value, the presentation
advances to the answer slide for that value. Click anywhere on the
slide after students guess the question, and the presentation
advances to the question that matches the answer that was given.
Click the question mark icon above “back to game” and the
presentation takes you back to the game board.
While playing the game in slide show view, don’t try to use
the four buttons that appear on the bottom left to navigate
the game. They won’t ever take you back to the game board.
