L.B.
Play the game Get Out of My Backyard! (I assume each player has their own ball at practice)
designate 1/2 the field as the backyard
All the balls are in the backyard
The coach and 2 players go into the backyard and start kicking the balls around
The other players yell Get Out of My Backyard and run into the yard and try to get all the balls away from the coach and other 2 players by kicking the ball into the net (once the ball is in the net it stays there)
if the coach or one of the 2 players originally in the yard get the ball away from a player that player is out of the game. Once all the balls are in the net the player still in the yard is the winner.
Another game:
Divide into 2 teams, one team with the coaches on it (Team A)(this team has less players)
Draw an imaginary line or real line with grass chalk and have each team stand on each side of the line facing each other.
The coaches should start kicking the balls over the line to team B. Team B should run and kick the ball back to the Coaches side, the coaches kick back to Team B etc... The idea is to be quick and try to get all the balls off your side.
The first team to have 0 balls on their side is the winner.
I have one more game: This is a race
Divide the girls into two teams
place 2 rows of soccer cones so the girls can maneuver around the cones with their ball
Have each team line up single file in front of the row of cones
When you say go, the first girl in line maneuvers the soccer ball around the cones until she gets to the end of the row of cones, she then turns around and makes her way through the cones back to her team mates once she gets back, the next girl in line maneuvers the soccer ball around the cones and then turns around and races back maneuvering through the cones, then the next girl etc...
The first team to finish is the winner
I hope that I explained these games well enough for you to understand, I am not that great at writing game rules.
Good Luck and have fun, I love soccer
