A visual timer students can read from across the room
A visible end point helps a class understand how much working time remains without repeated verbal reminders. Use the activity label to show exactly what students should be doing, then choose a preset or enter a custom time. The progress bar makes elapsed time understandable even for younger learners who do not yet read a digital clock confidently.
