  1. If New York is -15°, and Chicago is -10°, which city is colder?

  2. In this lesson you will learn that as the value of a negative number decreases, its absolute value increases by using a number line.

  3. |5| = 5 |-5| = 5

  4. |-6| < |-4.25| 6 1 0 2 3 4 7 8 9 10 -4 -3 -1 5 -10 -2 -9 -8 -7 -6 -5 l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l

  5. More Debt -$5 -$4 -$3 -$2 -$1 $0 $1 $2 $3 $4 $5 l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l Less Debt

  6. 15 ft. l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l 10 ft. S h a l l o w e r 5 ft. D e e p e r 0 Sea Level -5 ft. -10 ft. -15 ft.

  7. 15° C o l d e r New York -15° 10° l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l Chicago -10° 5° 0° -5° -10° -15°

  8. |-15| = 15 |-10| = 10 15 > 10 So |-15| > |-10| New York -15° Chicago -10°

  9. In this lesson you have learned that as the value of a negative number decreases, its absolute value increases by using a number line.

  10. 15° 10° l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l If Portland is -2°, and Seattle is -4°, which city is colder? 5° 0° -5° -10° -15°

  11. Using a number line, show that -$4.25 is more debt than -$3.50. Write an inequality that shows this relationship using absolute value. -$5 -$4 -$3 -$2 -$1 $0 $1 $2 $3 $4 $5 l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l l

  12. Ordering Cities • Using the Internet, find the elevation of several cities that are below sea-level. • Create a picture that shows the elevation of each city. • Order the cities from lowest to highest elevation. • Share your picture with your class.

  13. Which has the greatest absolute value, -6 or 7? Which of the following shows the greatest debt? • $-5.50 b. $-4.75 c. $-5.75 d. $-3.25
