Negative numbers help us to model many real world situations. How do I put positive and negative numbers in order?
 * Big Idea**
 * Essential Question #1**:

** A. Which team has the highest score? Which team has the lowest score? Explain. ** Rocket Scientist have the highest score because their score is in positive number. Kow-It-All has the lowest score because -500 is farthest from 0 in the number line. 650 points. **
 * Teams || Score ||
 * Super Brains || -300 ||
 * Rocket Scientists || 150 ||
 * Know-It-All || -500 ||
 * B. How many points separate the highest score and the lowest score? **

C. The dicussion above describes two possible ways the Rocket Scientists may have reached their score. Describe another possible way. For each of the other two teams, give one possible way the team could have reached their score. ** Super Brains= choose one 200 question and one 100 question and got both wrong. Rocket Scientists= Choose one 150 question and got it write. Know-It-All= Choose two 250 questions and got both wrong. **

D. What is each team's score now? ** Super Brain=-150 Roket Scientists=-150 Know-It-All= -300 E. Which team is in last place? ** Know-It-All is in last place. Follow Up
