A football team tries to move the ball forward as many yards as possible on each play, but sometimes they end up behind where they started. The distances, in yards, that a team moves on its first five plays are 2, 21, 4, 3, and 25. A positive number indicates moving the ball forward, and a negative number indicates moving the ball backward.

1). Which number in the list is the greatest?

2). What is a better question to ask to find out which play went the farthest from where the team started?

3). The coach considers any play that moves the team more than 4 yards from where they started a “big play.” Which play(s) are big plays?
