  1. How do you add -3 + (-6) and how does that relate to3 + 6 ?

  2. In this lesson you will learn to add two positive or two negative integers by using a number line.

  3. What’s an integer? Integers include positive and negative whole numbers as well as 0. ...-3, -2, -1, 0, 1, 2, 3 ... More Examples: -5 3 28 -9 1 0

  4. What’s addition? Addition is the process of joining two groups. 7 + 11 = 18 addend sum addend

  5. Adding two negative integers and getting a positive sum. -5 + (-7) = 12 - -5 + (-7) = -12

  6. Positive Direction Negative Direction Negative Numbers Positive Numbers

  7. 3 + 6 =9 Positive Direction 3 6 9 Positive Numbers

  8. -3 + (-6) =-9 Negative Direction -6 -3 -9 Negative Numbers

  9. 3 + 6 = 9 -3 + (-6) =-9

  10. In this lesson you have learned add two positive or two negative integers by using a number line.

  11. Simplify (-4) + (-7).

  12. What is the sum of 6 and 9?

  13. Try graphing two addition problems with opposite numbers on the same graph. • For example, use 12 + 8 and -12 + (-8). • Write about what you notice.

  14. Draw two number lines. On the first, graph -9 + (-13). On the second, graph -13 + (-9). • Compare and contrast the graphs.

  15. Partner Game: • Write the integers -20 through +20 on small pieces of paper and turn them face down. • You and your partner pull 2 numbers. Sum the integers by graphing the process on a number line. The person with the greater sum gets a point. Repeat.

  16. Simplify -9 + (-7). What is the sum of 6 and 13?
