Laughter, physical activity, and a ton of fun are guaranteed while playing Ba-Boom, a popular Recess Enhancement Program (REP) game. 



Who: Grades 3-8 

Players: 10+ 

Time: 10 minutes+ 

Where: Auditorium, cafeteria, classroom, gymnasium, hallway, library, playground 

Equipment: None 

How to Play 

  • Players form a circle, standing 6 feet apart from one another. 
  • The leader continuously says, “Ba, ba, ba.” Eventually the leader will say, “Boom!” 
  • When you hear BOOM you can choose to perform one of two actions: 
    • BA-BOOM - turn to someone on either side of you and clap-point while saying, “Ba-boom.”  
    • DUCK - squat and hold it. 
  • There are consequences for every action: 
    • If you ba-boom someone whose back is turned to you, then he or she does five jumping jacks. 
    • If you ba-boom someone who ba-booms you, then you both do five jumping jacks. 
    • If you duck while someone tries to ba-boom you, then the ba-boom passes over your head to the person next to you. 
    • If no one ba-booms anyone, then everyone does five jumping jacks! 

Check for Understanding 

  • What happens if someone ba-booms you in the back? 
  • What happens if no one ba-booms anyone? 

Game Tip  

  • Make sure to practice the commands and actions so that students are set up for success. 

Conflict Resolution Tip  

  • Have students play rock-paper-scissors if there are any disagreements. 


Easy: Mix up BOOM with words that rhyme.

Medium: Add SHIELD - players turn to someone on either side of them and put both hands up with their palms facing inward. If a player ba-booms a shield, then nothing happens. 

Hard: Add MIRROR - players turn to someone on either side of them and put both hands up with their palms facing outward. If a player ba-booms a mirror, then he or she must ba-boom the opposite way.
