- The document contains an agenda and lesson plan for a math class that includes reviewing operations with integers such as multiplication, division, addition and subtraction of integers. - It provides examples of integer word problems involving calculating total yards gained by football teams factoring in positive plays like rushing/passing yards and negative plays like sacks or penalties. - The summaries at the end provide the total yards calculated for different football teams based on the information given in each word problem scenario.

9. Practice with Word Problems
Figuring an offensive team’s total yardage gained is not just a case of adding up the numbers.
Players make positive plays, such as yards gained rushing and yards gained passing.
They also make negative plays, such as yards lost rushing or yard lost on a quarterback sack.
There are also penalties; they work both ways.
Examine the following game situations and figure the total yards gained by the team.
Introduction:

10. The Washington Redskins gained 256 rushing yards
in a game.
They also lost 4 yards on one play. The quarterback threw for 154 yards, but he was sacked seven times.
He lost a total of 53 yards on the sacks.
How many total yards did the Redskins gain?

11. In one game the San Diego Chargers gained 187 yards rushing and 458 yards passing. But they had 211 yards of
penalties against the offense.
How many total yards did they gain that night?

12. The New England Patriots are a passing team. They ran for only 47 yards last night, but they passed for 398. They
lost 38 yards on sacks, and they had three offensive penalties against them for a total of 25 yards.
How many total yards did they gain last night?

13. The Oakland Raiders only gained 75 yards passing and 62 yards rushing, but their opponent had 165 yards in
defensive penalties.
When you count all of their yards and all of the penalty yards, how many yards did the Raiders gain?

14. The following page(s) contains the answers to the tasks in the lesson activity.

17. The Washington Redskins gained 256 rushing yards in a game.
They also lost 4 yards on one play. The quarterback threw for 154 yards, but he was sacked seven times. He
lost a total of 53 yards on the sacks.
How many total yards did the Redskins gain?
353 total yards
256 -4 + 154 - 53
252 + 154 - 53
406 - 53

18. In one game the San Diego Chargers gained 187 yards rushing and 458 passing. But they had 211 yards of
penalties against
the offense.
How many total yards did they gain that night?
434 total yards
187 + 458 - 211
645 - 211

19. The New England Patriots are a passing team. They ran for only 47 yards last night, but they passed for 398. They
lost 38 yards on sacks, and they had three offensive penalties against them for a total of 25 yards.
How many total yards did they gain last night?
382 total yards

20. The Oakland Raiders only gained 75 yards passing and 62 yards rushing, but their opponent had 165 yards in
defensive penalties.
When you count all of their yards and all of the penalty yards, how many yards did the Raiders gain?
