Create Classroom Countdown Timers with PowerPoint

Kids are more focused and excited when completing tasks to a visual timer.  I use timers for learning centers, station activities, clean up, testing, and games; I'm sure you know a few other uses too.

I recently made an Exploding Head Countdown Timer (available for free at TeachersPayTeachers) 

but it is easy to create your own, check out the screencast below to learn how to create your own PowerPoint Countdown Timer.
