Mathletes Fab Five Directions: Write an integer to represent each situation. First, write down the number and question! 1) an elevator ride down 27 stories 1) -27 2) a $700 profit 2) 700 3) 46 degrees below zero 3) -46 4) a gain of 12 yards 4) 12 Additional Warm-Up Turn to page 4 in your GO MATH workbook Do Exercises 9 through 12. ANSWER: -9 -10 -4 -5 4 0 7 5 10 MODULE 1 Adding and Subtracting Integers MODULE 1 IntroAdding Video and (Click Here)Integers Subtracting Lesson 1.1 Adding Integers with the Same Sign Modeling Adding Integers Number Line Red and Yellow Tiles Examples: 1.) 2 + 4 = 6 Examples: 1.) -2 + (-2) = -4 is negative 0 2 2.) -2 + (-3) = -5 -5 -2 is positive 6 0 2.) 5 + 3 = 8 Vocabulary Word Absolute Value: The distance a number is from zero on the number line x Example: Find the absolute value. 1.) 3 = 3 2.) 2 = 2 Essential Question How do you add integers with the same sign? 1. Find the absolute values 2. Find the sum of the absolute values 3. Use the sign of the integers to write the sum Remember: Same sign add and keep!! Examples: Add the integers. 1.) -22 + (-16) -38 2.) -60 + (-13) -73 Same sign add and keep!! 3.) 125 + 35 160 Vocabulary Word Commutative Property Example: Add in any order 2 + 3 = 5 and you will get 3+2=5 the same sum a+b=b+a 5+6=6+5 Adding more than two terms Use the Commutative Property to help add more simple numbers Examples: 180 64 20 200 264 Homework • Workbook Page 10 (#1-17 ALL)
