@ClassTechTips Timing is one of those tasks. The mental energy spent tracking "how long has this actually been" adds up. A visible classroom timer takes that off your plate — students self-regulate and you stop being the timekeeper.
Built one if you're curious: countdownclock.net/classroom
Genuine question for teachers: what do you use timers for that most people wouldn't think of?
Transitions and tests are obvious. I keep hearing about uses I hadn't anticipated when I built this.

Tip: during tests, project the timer at the edge of the screen, not center.
Out of direct sightline for most seats. Visible when needed, not a distraction when not.

A small thing that changed how I think about classroom timers:
The timer isn't for the teacher. It's for the students to self-regulate without you having to be the timekeeper.
Once I started designing for that, the whole UX got simpler.

The "5 more minutes" timer — when you said 5 more minutes but it's been 12 and the kids have noticed.
