1. Chapter 2 Integers and Rational Numbers (take out chapter 1 from your notebook and leave ch1 stuff at home in a folder to study off of for star test and final project)

2. 2.1 Integers and the Number Line Objectives: 1.To give an integer that corresponds to a real-world situation 2.To compare integers using 3.To find the absolute value of a number

3. Integers Any number such as... –4, -3, -2, -1, 0, 1, 2, 3, 4... Positive Integers are greater than zero. Negative Integers are less than zero. “Zero” is neither positive or negative.

4. Number Line 042-6-4-2 6

5. Two numbers are OPPOSITES of one another if they are the same distance from zero but in opposite directions. 042-6-4-2 6 6 and -6 are opposites.

6. 4 and -4 are opposites 042-6-4-2 6

7. Absolute Value: The number of units a number is from zero on the number line. (Always Positive) 042-6-4-2 6 |-4| = 4

8. Absolute Value: (Always Positive) 042-6-4-2 6 |6| = 6

9. Find the Opposite and the Absolute Values of -7 042-6-4-2 6

10. Find the Opposite and the Absolute Values of -7 042-6-4-2 6 Opposite of –7 is 7 7 units

11. Find the Opposite and the Absolute Values of -7 042-6-4-2 6 |-7| = 7 7 units

12. Evaluating Absolute Value Before you evaluate find the absolute value of the number then do the operation Example: -5 + 4 = 5 + 4 = 9

13. Example: Evaluate t – 15 for t = -36 = -36 -15 =36-15 =21

14. Write an integer that means “a profit of $4 +4

15. Write an integer that means “12 yards gained” +12

16. Write an integer that means “a loss of 73 points on the NASDAQ” -73

17. Write an integer that means “losing 11 pounds on a diet” -11

18. INCREASERIGHT On a number line, values INCREASE as you go RIGHT 0 42 -6-4-2 6

19. Big Number > Little # Or Little # < Big NumberLittle # < Big Number

20. True or False? -5 < 7 042-6-4-2 6 True

21. True or False? -6 < -2 042-6-4-2 6 True

22. True or False? 6 < 0 042-6-4-2 6 False

23. True or False? -6 > 5 042-6-4-2 6 False

24. Write the integers –4, 5, 3, -2, and 0 from least the greatest. 042-6-4-2 6 -4, -2, 0, 3, 5
