 * Big idea:**Negative numbers help us to model many real world situations.
 * Essential question:** How do I put positive and negative numbers in order?
 * Notes from class:** is there a faster way of finding the number between two numbers other then using then number line?


 * __1.3__

A. Arrange the following temperatures in order from lowest to highest.**

-15',-8',-2',0',4',12'

1.** 15'F
 * B. The temperature reading on a thermometer is 5'F. Tell what the new reading will be if the temperature
 * 2.** 3'F
 * 3.** -5'F
 * 4.** 12'F

1.** -8'F
 * C. The temperature reading on a thermometer is -5'F. Tell what the new reading will be if the temperature
 * 2. -**2'F
 * 3.** -15'F
 * 4.** 5'F

1.** 5'
 * D. In 1-6, give the temperature halfway between the two given temperatures.
 * 2.** 5'
 * 3.** -5'
 * 4.** -10'
 * 5.** 0'
 * 6.** -11'

1.** 6'
 * E. In 1-4 tell which temperature reading is farther from -2'F.
 * 2.** same
 * 3.** 2'
 * 4.** -10'


 * F. Explain how you determined your answer for part 4 of question E.**

I made the number line and compared to see which was closer to -2'. It turned out that -10' was farther away from -2'


 * __F.U__**

a. 7 b. -18 c. 42 d. 0
 * 1. Give the opposite of each number.**

0 and -4. No they are not opposites because it doesn't start from zero.
 * 2.Name two numbers on the number line that are the same distance from -2. Are these numers opposites?**

team B, team E, team D, team A, team C.
 * 3.Order the teams from first place through fifth place.**


 * 4. draw a number line. Mark and label each team's score. Label the point for each team with both team letter and the score.**



100
 * 5. On the number line, what is the distance between the scores of Team A and Team B?**

-250
 * 6. On the number line, what is the distance between the scores of Team C and Team A?**

100
 * 7.On the number line, what is the distance between te scores of Team D and Team E?**


 * 8. Tell how each team, by answering one question, could change their score to 0. Give the point value of the question, and tell whether the team must answer the question correctly or incorrectly. If this is not possible for a particular team, explain why.**

team A: Must answer 50pt question correctly team B: Must answer 150pt question incorrectly team C: Must answer 300pt question correctly team D: Is not possible because its already 0. team E: Must answer 100pt question incorrectly
