Objective of the Game

Each team has an end zone that it attempts to protect, and points are awarded for the team that successfullyreaches its opponent's end zone. The completion of that task is known as a touchdown, which awards thescoring team six points. The team with the most points at the end of the game wins.

Game Layout

A football game is divided into four quarters. Lengths of quarters vary based on the level of play. Between thesecond and third quarters is a short break, known as halftime. During that time, both teams usually retreat tothe locker rooms to rejuvenate and discuss strategies.

Scoring

Touchdown - Six points awarded to a team that crosses their opponents goal l ine with the football. Field Goal - A three-point play made by place kicking (or drop kicking) the ball between the opponent's

goalposts above the crossbar. Extra Point - After a touchdown, the scoring team is allowed to add another point by kicking the ball through

the uprights of the goalpost.

Two-point conversion - Instead of kicking an extra point, a team tries to add two bonus points by running orcompleting a pass in the end zone from the opponents two-yard line.

Safety - A play in which a member of the offensive team downs the ball in his own end zone, resulting in thedefensive team being awarded two points.

Field Dimensions

A football field is 100 yards long with two 10-yard end zones at either end. Width-wise, a field measures 53yards across. Every yard on a football field is marked with a small yard-marker on the horizontal boundariesof the field. Every five yards there is a horizontal line that extends from sideline to sideline. Typically, every 10

yards is visually displayed on the field with the corresponding number. Thus, the numbers on a field wouldread 10, 20, 30, 40, 50, 40, 30, 20, 10 from one end of the field to the other.

Downs

A team is given four downs to obtain a first down, which is located 10 yards from the initial first-down spot.Each down is started with the snap of the ball from what is called the line of scrimmage. The snap is theprocess by which the center passes the ball through his legs to the quarterback. If a player is tackled whileholding the ball, the next play starts from that yard-marker. If the quarterback throws the ball and it is notcaught, the ball returns to the same spot it had been on the previous down. On fourth down, a team maychoose to go for the first down, kick a field goal for three points or punt the ball. Punting means kicking theball to the other team to avoid turning it over after four downs. A failed fourth down attempt results in thedefending team taking over possession at the spot of the failed attempt.

Tackling

A tackle is the action that causes a play to end. If a player with the ball hits the ground with his knees,elbow or any part of the body other than his feet and hands, he is down at that spot. The process ofknocking that player down or pulling him down to the ground is known as a tackle. It is often aviolent collision which brings about the need for helmets and pads for protection.

Referees and Penalties

The men wearing the zebra-striped uniforms are known as officials. The head official is the referee.He announces penalties. There are numerous penalties in the game of football, each signified when anofficial throws a yellow flag onto the field. Penalties are assessed by moving the ball backward acertain number of yards. Penalty values are typically given as 5 yards, 10 yards or 15 yards. As thereferee announces the penalty, he simultaneously performs a gesture that is associated with theinfraction. This ritual came about prior to the invention of microphones and loudspeakers
