Presentation Transcript

Slide 2: 

One 11-man team has possession of the football. It is called the offense and it tries to advance the ball down the field by running with the ball or throwing it – and score points by crossing the goal line and getting into an area called the end zone. OFFENSE GOAL LINE

Slide 3: 

The other team (also with 11 players) is called defense. It tries to stop the offensive team and make it give up possession of the ball. If the team with the ball does score or is forced to give up possession, both teams switch roles. And so on, back and forth, until all four quarters of the game have been played. DEFFENSE

Slide 4: 

100 yards (91 mts) long and 53 yards wide (48 mts)

Slide 5: 

End zone: It's an additional 10 yards on each end of the field. When the offense gets the ball into the opponent's end zone, they score points.

Slide 6: 

Games are divided into four 15-minute quarters, separated by a 12-minute break at halftime. There are also 2-minute breaks at the end of the first and third quarters as teams change ends of the field after every 15 minutes of play.

Slide 7: 

At the end of the first and third quarters, the team with the ball retains possession heading into the following quarter. That is not the case before halftime. The second half starts with a kickoff in the same way as the game began in the first quarter.

Slide 8: 

TOUCHDOWN = 6 POINTS It is the biggest single score in a football game. It is worth six pts, and it allows the scoring team an opportunity to attempt to get an extra point. To score a touchdown, the ball must be carried across the goal line into the end zone, caught in the end zone, or a fumble recovered in the end zone, or an untouched kickoff recovered in the end zone by the kicking team. TOUCHDOWN

Slide 9: 

EXTRA POINT and the TWO-POINT CONVERSION = 1 or 2 POINTS Immediately following a touchdown, the ball is placed at the opponent's two-yard line, where the offense has two options. Usually the offense will kick an extra point. If the offense successfully kicks the ball through the goal posts, it earns one point. The offense can also score two points by running or throwing the ball into the end zone in the same manner as you would score a touchdown. Since going for two points is more difficult than kicking an extra point, the offense generally chooses to kick the extra point.

Slide 10: 

FIELD GOAL = 3 POINTS If the offense cannot score a touchdown, it may try to kick a field goal. Field goals are worth three points and often are the deciding plays in the last seconds of close games. They can be attempted from anywhere on the field on any down, but generally are kicked from inside the defense's 45-yard line on fourth down. For a field goal to be "good", the placekicker (or field goal kicker) must kick the ball through the goal-post uprights and over the crossbar. The defense tries to block the kick and stop the ball from reaching the goal post.

Slide 11: 

SAFETY = 2 POINTS The safety is worth two points. A safety occurs when the offensive ball carrier is tackled (football move to stop the player from gaining ground towards goal) behind his own goal line.
