neckerchiefs or ribbons

define the playing field - basketball court size is good.
Divide group into 2 teams.
Put neckerchiefs on 1 team's arm for identification.

One team starts with the ball.
It is thrown to another teammate who yells "One!"
At each successful catch, the next number is yelled.
When a team reaches "Ten!" they receive one point.

The other team tries to intercept the ball or knock it to the ground.
On an interception, the scout yells "One!" and his team is now counting up.
When the ball hits the ground, the team that was last counting loses control and the other team picks it up and starts counting up.

The only physical contact should be incidental while going for the ball.

Set a time limit or first team to a specific score.
