Lessons 9 Student Outcomes

• Students compare and interpret rational numbers' order on the number line, making statements that relate the numbers' location on the number line to their order.
• Students apply their prerequisite knowledge of place value, decimals and fractions to compare integers and other rational numbers.
• Students relate integers and other rational numbers to real world situations and problems.

Lesson 9 Summary
• The number associated with the point on the right is greater than the number associated with the point on the left.
• Whichever number is graphed farthest to the left is the smaller number.

Lesson 9 Classwork

Exercises 2
For each problem, determine if you agree or disagree with the representation. Then defend your stance by citing specific details in your writing.
2. Felicia needs to write a story problem that relates to the order in which the numbers −6 1/2 and -10 are represented on a number line. She writes the following:
“During a recent football game, our team lost yards on two consecutive downs. We lost 6 1/2 yards on the first down. During the second down our quarterback was sacked for an additional 10 yard loss. On the number line, I represented this situation by first locating −6 1/2. I located the point by moving 6 1/2 units to the left of zero. Then I graphed the second point by moving 10 units to the left of 0.” Lesson 9 Problem Set

Write a story related to the points shown in each graph. Be sure to include a statement relating the numbers’ graphs on the number line to their order.

1. Interpret the number line diagram shown below and write a statement about the temperature for Tuesday compared to Monday at 11:00 p.m.

2. If the temperature at 11:00 p.m. on Wednesday is warmer than Tuesday's temperature, but still below zero, what is a possible value for the temperature at 11:00 p.m. Wednesday?
