A few years ago, someone showed me how to embed a timer in a Google Slide presentation. This has become a staple in my classroom. I embed a YouTube Video in the corner of the objective slide when I know that I want a visible countdown.
- Students like to know when an activity should be finished.
- Students who might finish early have a tendency to continue working/exploring when the timer is on the screen.
- It helps me keep track and not miss my transitions.
