• Passing involves moving the ball to a teammate, which means effective passing can break down defensive setups
• Shooting is attempting to score by throwing the ball into the hoop and includes various techniques like jump shots, layups, and three-pointers
• Defense, teams use various defensive strategies to prevent the opposing team from scoring
• Man-to-man defense involves each player guarding a specific opponent
• Zone defense involves players guarding specific areas of the court
• Rebounding involves retrieving the ball after a missed shot, which leads to giving a team additional scoring opportunities and prevent the opposing team from scoring

Basic Rules
