Choose your bomb
Any bomb you pick runs for 15 minutes. Three bombs are free forever, and nine more are ready whenever you want the whole crew.
Other timer lengths
Fifteen minutes covers real work. This free 15 minute bomb timer fits independent reading, writing workshop, chore charts, and practice sessions: the moments when focus needs to stretch but attention still wants a visible endpoint.
In rotations, fifteen minutes is the standard station length for upper elementary. Project the bomb and each group paces itself without asking how long is left. The big digits stay readable from the back row of the classroom.
At home it is the perfect room-cleaning length for bedrooms that got out of hand. For shorter resets use the 5 minute bomb timer; for test blocks and bigger projects, step up to 20 or 30 minutes.
