How to Add a Timer to PowerPoint Slides

I recently received this email from a reader who was looking for help adding a timer to her PowerPoint slides,

"I need your help adding a timer to already made quizzes in PowerPoint. I need a timer that shows 30 minutes. I would like the timer to be seen at the top right corner on all slides so students can see how much time they have left during a quiz."

My suggestion is to try the Timer Slice PowerPoint Add-in. In the video embedded below I demonstrate how to add a timer to PowerPoint slides by using Timer Slice.

There are other methods for adding timers to PowerPoint slides. You can use this animation method described in detail by Microsoft. You can also use and modify the timer templates available in the PowerPoint templates gallery.
