Ok, it is called "Polish Baseball" not football.
Here is how it is done.
1) The kids are divided equally in two teams.
2) The team number one lines up before the batter. The other team spreads out in the field.
3) Use a rubber red ball, that they usually use for dodgeball in school. The pitcher tries to throw the ball to the batter. The batter hits it.
4) Once the batter hits the ball, he has to run around his team's line. Each time he makes a complete run around, the team gets a point. He stops running when...
The other team has to get the ball, then form a line behind the ball person. Each team member must successfully pass the ball to the back of the line WITHOUT dropping the ball. When the last person gets the ball, the batter stops running. Points are summed up by how many times the batter ran around his line.
5) Each team continues this until 3 outs (if ball is catched before it touches ground, that is an out.) Switch around, etc... I forgot how many innings or what maximum points to win the game, but I guess the team who has most points from running around the line wins.
Questions? Ask away...
Edited to add the following:
When the other team tries to pass the ball, they have to line up like a normal line behind the ball person. The ball person puts the ball under him between his legs to the next person. The next person gets it and passes it under him through his legs to next person. I hope I am clear on this.
