QUIET BALL: For those relaxed moments (ha-ha-ha)
  
  Author: Jean 

  Procedure:

        Students get on their knees on top of their desks.

        They pass the ball 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 one. Kids love to play it. I use a
        nerf ball.
