I've written about a bunch of timer websites and apps in the past (here's a list of five). Today, I found another nice timer tool that teachers may find handy. Timer Pop allows you to create and save multiple timer settings. For example, if I want to have a count down that lasts for five minutes, a count down of fifteen minutes, and a count down of three minutes I can save them all. Then when I need one of them I'll just click on it to start the count down.
Applications for Education
Whenever I have long blocks of instructional time I like to break it up with short breaks and or timed hands-on activities. One tool that can help to prevent the students and me from stretching the "break times" is to use a countdown timer like Timer Pop.
