I will give two games as examples of helping solve this tactical problem, one for soccer and one for volleyball.
Soccer: Relay Game
Divide the group up into however many teams are wanted to keep the teams relatively small, and have each group line behind each other. Select one player from each team to be a defense man for another team. The goal is for each player in the group to make their way across the field to the goal and score a point, but they must first get past the defense man guarding it. If the defense man manages to gain possession of the ball or kick it away, the player must start the relay again.
Before the game starts, though, provide the students/players with tactics that might help them solve this problem, such as moving to open space, dodging, guarding and footwork, and faking. See how many of these tactics the group uses and which ones they find to work the best for them.
The first group to have all of their teammates successfully finish the rely wins the match.
Volleyball: 2 vs. 2
Have the class split up into groups of four and find a place at one of the nets, 2 on each side. Each team will work together to try and solve the tactical problem of getting past their peers to score a point for their team. To do this, they will have to try and find a way to first hit the ball in a way that will make it more difficult to return and second to try and find an open space to hit it to, instead of passing it directly to the other team. For example, if both of the teammates on the opposing team are closer to the net, tell the player to try spiking the ball to the back of the court where they will have to work harder to return the ball.
Once again, provide the class with tips on how to solve this tactical problem, such as ways to hit the ball and how to direct in a certain direction.
