This PowerPoint file contains five timers for using in PowerPoint. These simple timers are intended as task timers. There are five timer durations, 1 to 5 minutes. There are four versions of each timer: start with slide, start with and end with green, start on click, start on click and end with green.
Preview of the 1 minute timer:
To use, go to the slide with the timer you want. Highlight the whole timer, copy and paste into your own presentation.
Note, these timers are not highly accurate - whilst I display the duration as 1 minute, PowerPoint has a limit of 59 seconds... close enough.
