What are the different ways to score in American football?

The most common way to score in American football is a touchdown, which is worth 6 points. After each touchdown, you have the option of scoring 1 or 2 points during the "extra point". Many teams elect to kick field goals when they can't get close enough to score a touchdown. Field goals are worth 3 points each. Defensive players can also score a safety, which is worth 2 points.
