Presentation Transcript

  1. MathletesFab Five • an elevator ride down 27 stories • a $700 profit • 46 degrees below zero • a gain of 12 yards Directions: Write an integer to represent each situation. First, write down the number and question! • -27 • 700 • -46 • 12

  2. Additional Warm-Up Turn to page 4 in your GO MATH workbook Do Exercises 9 through 12. ANSWER: -9 -4 4 7 -10 -5 0 5 10

  3. Module 1 Adding and Subtracting Integers

  4. Module 1 Intro Video (Click Here) Adding and Subtracting Integers

  5. Lesson 1.1 Adding Integers with the Same Sign

  6. Modeling Adding Integers Number Line Red and Yellow Tiles Examples: 1.) -2 + (-2) 2.) 5 + 3 = 6 = -4 Examples: 1.) 2 + 4 2.) -2 + (-3) is negative 0 2 6 is positive = -5 = 8 -5 -2 0

  7. Vocabulary Word Absolute Value: The distance a number is from zero on the number line Example: Find the absolute value. = 3 = 2

  8. Essential Question How do you add integers with the same sign? • Find the absolute values • Find the sum of the absolute values • Use the sign of the integers to write the sum

  9. Remember: Same sign add and keep!!

  10. Same sign add and keep!! Examples: Add the integers. 1.) -22 + (-16) 2.) -60 + (-13) 3.) 125 + 35 -38 -73 160

  11. Vocabulary Word Example: 2 + 3 = 5 3 + 2 = 5 Commutative Property Add in any order and you will get the same sum a + b = b + a 5 + 6 = 6 + 5

  12. Adding more than two terms Use the Commutative Property to help add more simple numbers

  13. Examples: 200 264
