1.
With an adult, choose an outdoor paved area that is clean, safe, and free from traffic. Use Sidewalk Chalk to draw a circle about 1 foot (30 cm) in diameter.
2.
Draw an outer shooting circle around the first, about 6 feet (180 cm) in diameter.
3.
Start with four marbles per person. Each player places three marbles inside the smaller circle and keeps one as a shooter.
4.
To shoot a marble: Balance the marble in the hollow made by curling the index finger around and above a straight thumb. Hold the hand on or close to the ground. Take aim and flick the thumb forward at the target.
5.
Players take turns shooting a marble at the others, trying to knock one out of the larger circle. If a player succeeds, the marble knocked out becomes the property of the shooter. The shooter retrieves the shooting marble after each try.
