1 TwoColor Counters Adding Integers, Part II Learning Goals In this lesson, you will: Key Term additive inverses Model the addition of integers using twocolor counters. Develop a rule for adding integers. Opposites are all around us. If you move forward two spaces in a board game and then move back in the opposite direction two spaces, you re back where you started. In tugofwar, if one team pulling on the rope pulls exactly as hard as the team on the opposite side, no one moves. If an element has the same number of positively charged protons as it does of negatively charged electrons, then the element has no charge. In what ways have you worked with opposites in mathematics? 4.3 Adding Integers, Part II 215
2 Problem 1 TwoColor Counters 1. Use the number line model to determine each sum. a. 3 1 (23) b. (214) c. 8 1 (28) d. What pattern do you notice? Two numbers with the sum of zero are called additive inverses. Addition of integers can also be modeled using twocolor counters that represent positive (1) charges and negative (2) charges. One color, usually red, represents the negative number, or negative charge. The other color, usually yellow, represents the positive number, or positive charge. In this book, gray shading will represent the negative number, and no shading will represent the positive number Chapter 4 Addition and Subtraction with Rational Numbers
3 You can model the expression 3 1 (23) in different ways using twocolor counters: (3) 3 Three positive charges and three negative charges have no charge. 3 1 (23) 5 0 (3) 3 Each positive charge is paired with a negative charge. 3 1 (23) What is the value of each and pair shown in the second model? 3. Describe how you can change the numbers of and counters in the model, but leave the sum unchanged. 4.3 Adding Integers, Part II 217
4 Let s consider two examples where integers are added using twocolor counters. Example 1: There are 13 positive charges in the model. The sum is 13. Example 2: 5 1 (28) There are five pairs. The value of those pairs is 0. There are 3, or negative charges, remaining. There are 3 negative charges remaining. The sum of 5 1 (28) is Create another model to represent a sum of 23. Write the appropriate number sentence. 218 Chapter 4 Addition and Subtraction with Rational Numbers
5 5. Share your model with your classmates. How are they the same? How are they different? 6. Write a number sentence to represent each model. a. b. c. d. e. f. 4.3 Adding Integers, Part II 219
6 7. Does the order in which you wrote the integers in your number sentence matter? How do you know? 8. Write each number sentence in Question 6 a second way. 9. Draw a model for each, and then complete the number sentence. a (24) 5 b c. 9 1 (24) 5 d Chapter 4 Addition and Subtraction with Rational Numbers
7 10. Complete the model to determine the unknown integer. a b c Describe the set of integers that makes each sentence true. a. What integer(s) when added to 27 give a sum greater than 0? Consider drawing a number line model or a twocolor counter model to help you answer each question. b. What integer(s) when added to 27 give a sum of less than 0? c. What integer(s) when added to 27 give a sum of 0? 4.3 Adding Integers, Part II 221
8 12. When adding two integers, what will the sign of the sum be if: a. both integers are positive? b. both integers are negative? c. one integer is negative and one integer is positive? What happens when you add a negative and a positive integer and they both have the same absolute value? 13. Write a rule that states how to determine the sum of any two integers that have the same sign. 14. Write a rule that states how to determine the sum of any two integers that have opposite signs. 222 Chapter 4 Addition and Subtraction with Rational Numbers
9 15. Use your rule to determine each sum. a (24) 5 b (215) 5 c (212) 5 d e (213) 5 f g (225) 5 h (237) Determine each unknown addend. a. 1 (225) 5 34 b c d e f Talk the Talk Represent the sum of additive inverses in the graphic organizer provided. First, write a number sentence. Then, represent your number sentence in words, using a number line model, and using a twocolor counter model. Be prepared to share your solutions and methods. 4.3 Adding Integers, Part II 223
