  6. Lesson 2 Contents Example 1Compare Integers Example 2Order Integers

  7. Example 2-1a Replace the  with < or > to make –9  –5 a true sentence. Write the problem using a circle for the comparison - 9 - 5 We know that 9 is larger than 5 but when they are negative the inverse is true We can see this on a number line Plot - 9 Answer: –9 < –5 Plot - 5 1/2

  8. Example 2-1b Replace the  with < or > to make –3  –6 a true sentence. Answer: –3 > –6 1/2

  9. MULTIPLE-CHOICE TEST ITEMThe lowest temperatures in Europe, Greenland, Oceania, and Antarctica are listed in the table. Order the temperatures from least to greatest. Continent Record Low Temperature (°F) A –67, –87, 14, –129 B 14, –67, –87, –129 C –129, –87, –67, 14 D –67, –87, –129, 14 Europe –67 Greenland –87 Oceania 14 Antarctica –129 Example 2-2a 2/2

  10. Continent Record Low Temperature (°F) Europe –67 Greenland –87 Oceania 14 Antarctica –129 Example 2-2a Begin with the negative numbers Remember: The bigger a number looks, the smaller it is when it is negative Negative 129 is the smallest number Negative 87 is the next smaller number -129, -129, -87, -129, -87, -67, Negative 67 is the next smaller number 2/2

  11. Continent Record Low Temperature (°F) Europe –67 Greenland –87 Oceania 14 Antarctica –129 Example 2-2a 14 is the only number remaining that has not been used Choose the appropriate answer A –67, –87, 14, –129 B 14, –67, –87, –129 C –129, –87, –67, 14 D –67, –87, –129, 14 -129, -129, -87, -129, -87, -67, -129, -87, -67, 14 Answer: C 2/2

  12. MULTIPLE-CHOICE TEST ITEMThe lowest temperatures on a given day in four cities in the United States are listed in the table.Order the temperatures from least to greatest. City Low Temperature A –3, –6, 7, –12 B –12, –6, –3, 7 C –12, 7, –6, –3 D 7, –3, –6, –12 Portland, OR –12 New York City, NY –6 Denver, CO 7 Newport, RI –3 Example 2-2b * Answer: B 2/2
