Hi Michael, there are a couple of ways you could do this. One is tell them this lesson will take 20 minutes and they can look at the clock on the computer, phone or watch. This is probably the simplest way and takes up the least screen space.

Take a look at the attached file if you want to have a clock on the screen. This gives you a rough idea on how to set up a timer. It would have to be on the Master Slide so it would appear on all the other slides. To make it a little more realistic you could add a 10 second box so that a zero would appear. You would probably want to find a good font to mimic a digital clock also.
