Applying Addition and Subtraction of Integers

Warm Up

In a football game, a team had a gain of 10 yards, a loss of 5 yards, a loss of 2 yards, and a gain of 4 yards in the first 4 plays. Write and evaluate an expression to find the team’s change in position.

Over a period of four hours, the temperature rose 3⁰F, rose 2⁰F, dropped 4⁰F, and dropped 1⁰F. If the starting temperature was -2⁰F, what was the temperature after four hours?

What is the total change in Mei’s checking account if she writes a $35 What is the total change in Mei’s checking account if she writes a $35.00 check for shoes, deposits $50.00, and then writes a $55.00 check for a sweater?

In round 1 of a game, a student loses 5 points, loses 3 points, gains 17 points, and loses 7 points. What is the student’s score at the end of round 1?

Exit Ticket -7 + 11 – 6 + 8 = 40 – 16 + 10 = -20 + 18 + 30 = The Possums were on their 20 yard line. On the next four plays they gained 1 yard, lost 8 yards, lost 12 yards, and gained 24 yards.
