Scatter the jacks on the ground in front of yourself, and…

  • Toss the ball (upward) with the right hand.
  • Grab the jack(s) with the right hand, and then quickly transfer them to the left, while allowing the ball to bounce.
  • Catch the ball with the right hand; keep holding the jack(s) with the left.

…And repeat the steps until all jacks are captured.

Start off with Onesies and continue on with Twosies, Threesies, Foursies, etc.; all the way up to Tensies.
