A) The relay race is just over one mile long, approximately "1,760" "1" /"4" yards. If Jack and 4 other people each run a leg of the relay, how many yards will each runner run? Justify your answer using an estimation strategy. (3 points) The relay was an exciting event! The eighth graders earned 200 points.
b)During the shot put event, Alayna throws the ball 32.45 feet while her teammates throw
28.34 feet, 26.59 feet, and 33.11 feet. Use an estimation strategy to determine about how many total feet were thrown by the team. Describe the estimation strategy you used to solve the problem. (2 points)

If the team threw the shot put more than110 feet, then the seventh graders earn 110 points. If not, then the eighth graders earn 110 points. Which grade should be awarded 110 points?

Step 5: Adding and subtracting with rational numbers
Alex, an eighth grader, and Eric, a seventh grader, need to determine who came closer to their grade’s state record for the triple jump. Alex jumped 39.85 feet and Eric jumped 37 feet and "1" "1" /"4" inches. Who was closer to the state record if the eighth-grade record is 42.25 feet and the seventh-grade record is 39 feet 3 inches? (2 points)

If a seventh grader gets closer to the record-setting jump, then the seventh graders earn 100 points. If not, the eighth graders earn 100 points. Which grade should be awarded 100 points?

Step 6: Using the commutative and associative properties of multiplication to simplify multiplication of two rational numbers

a)The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of students in seventh and eighth grade combined is 584; "5" /"8" of them are seventh graders and "3" /"8" of them are eighth graders. If "4" /"5" of the seventh graders participated in track-and-field day and "7" /"8" of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer. (4 points)

b) Each team earns 1 point for each person who participated in the track-and-field day. Who wins the meet—the eighth graders or the seventh graders? Explain. (2 points)
