Somewhere around minute 35 of a block period, attention falls off a cliff. Younger kids get a song and a stretch. High schoolers get a teacher talking louder.
Teens need a reset too. It just has to feel like something a teenager would do.
Quick resets that work
Stand and switch: everyone stands, finds a partner across the room, and explains the last thing you covered in 30 seconds.
Two-minute debate: a quick, silly would-you-rather. Left side of the room versus right side.
Stretch and sort: students stand, and you read statements. True, they stay standing. False, they sit.
Silent 60: one minute of no screens, no talking, eyes closed or looking out a window. It sounds odd. Students ask for it later.
Doodle summary: 90 seconds to sketch what the lesson is about so far, no words allowed.
Keep it short and tied to class
A good brain break is under three minutes and ends with a clear signal back to work. The best ones review content while they reset energy, so you don't lose any instructional time.
Use them on a schedule
Don't wait until the room falls apart. In a 90-minute block, plan a reset every 20 to 25 minutes. In a 50-minute class, one in the middle is usually plenty.
