Students pass the beachball back and forth. If anyone talks or makes a noise, they have to sit down. Also if someone throws the ball so another person can’t possibly catch it, the person throwing has to sit down. If the ball is thrown so the person could catch it but doesn’t, the person catching the ball has to sit down. It’s a process of elimination and kids love it. It requires teacher as referee, but it does afford a few quiet moments when you really need a few. Kids love to play it.
