Set up a defined dribbling area with cones or discs. I recommend 20-40 yards square depending upon age. Each player has their own ball. The game begins with all players dribbling around within the defined area. The coach then chases the players trying to tag them. When a player is tagged, they must freeze, hold the ball high above their heads, and spread their feet apart. The player remains frozen until a teammate dribbles their own ball through the frozen player's legs, after which the player is unfrozen and continues dribbling around.

You may want to have a second or even third coach help with the chasing. Older kids can take turns as the chaser as well. Other options include setting up cones or discs as obstacles within the play area that players can dribble around, practice moves with, etc.

This is a great dribbling game that also encourages teammates to help each other out.

Reader Suggestion:
As the chasers sneak up on the players, have the kids warn each other by yelling "Man On!". This further promotes teamwork and starts a good habit for when the kids get older.
