Here is a Jeopardy game for your classroom visits. The game must be in the PRESENT mode for it to work. Many classrooms have projection technology such as a SmartBoard.
Below is the PowerPoint version which is a copy from the original google document above. The game must be in the SLIDESHOW mode for it to work. Since it is a copy, the money amounts on the game board do not pop visually but the game works. I suggest the google version above.
