Young kids love Capture The Flag. Introduce aspects from that game to create a fun and competitive dribbling drill.
Every player has a ball and two flags. Create teams of 2. Use markers to set up a home base for each team. The goal of the game is to steal flags from the other teams and return them to your base. Players must dribble while playing the game.
Play for a set amount of time and the team with the most flags at the end wins.
