Two In One

So my students are playing Jeopardy this week to review for their test. That means that the PowerPoint will be on the board and I am at my desk waiting for them to answer the question. For me I can be doing things like taking attendance, checking my emails, or working on something while they are doing the Jeopardy. I learned how to turn on the duel monitor and have the PowerPoint on the overhead screen and I can still work on other things without the students knowing. If anyone wants the secret, just ask.
