Compare and Order Integers At the end of this lesson you should be able to answer the following question. How can symbols and absolute value help you order sets of integers? Integers The number line can be used to compare and order integers. On a number line, the number to the left is always less than the number to the right. Integers An inequality is when two values are not equal. e.g. 6 > 3 Integers Write -9 and -4 as an inequality. Integers Write -9 and -4 as an inequality. -9 -4 -9 < -4 Generally you want to keep the integers in the same order as in the question. Integers Write -5 and 0 as an inequality. Integers Write -5 and 0 as an inequality. -5 -5 < 0 0 Integers Replace with < or > to make the statement true. -6 5 -5 0 Integers Replace with < or > to make the statement true. -6 5 -5 0 Since -6 is to the left of 5 it is less than 5. -6 < 5 Integers Replace with < or > to make the statement true. -1 0 -5 0 Integers Replace with < or > to make the statement true. -1 0 -5 0 Since -1 is to the left of 0 it is less than 0. -1 < 0 Integers Justin has a score of -4 on the Trueville Trivia game. Desiree’s score is -5. Write an inequality to compare the scores. Who has the higher score? Integers Justin has a score of -4 on the Trueville Trivia game. Desiree’s score is -5. Write an inequality to compare the scores. Who has the higher score? -4 > -5 Integers Justin has a score of -4 on the Trueville Trivia game. Desiree’s score is -5. Write an inequality to compare the scores. Who has the higher score? -4 > -5 -4 is further to the right than -5, so Justin has the higher score. Integers The temperature on Tuesday was 2˚F. The temperature on Wednesday was -2˚F. Write and inequality to compare the temperatures. Explain the meaning of the inequality. Integers The temperature on Tuesday was 2˚F. The temperature on Wednesday was -2˚F. Write and inequality to compare the temperatures. Explain the meaning of the inequality. 2 > -2 Integers The temperature on Tuesday was 2˚F. The temperature on Wednesday was -2˚F. Write and inequality to compare the temperatures. Explain the meaning of the inequality. 2 > -2 2 is further to the right than -2, so Tuesday’s temperature was higher. Integers Order 4, 8, 0, -5 from least to greatest Do this on your own. (use your number line) Integers Order 4, 8, 0, -5 from least to greatest -5 0 4 8 Integers Order 4, 8, 0, -5 from least to greatest -5 0 4 8 Is least to greatest right to left or left to right? Integers Order 4, 8, 0, -5 from least to greatest -5 -5,0,4,8 0 4 8 Integers Order 1, -3.5, 4, -1.5 from least to greatest Integers Order 1, -3.5, 4, -1.5 from least to greatest -3.5, -1.5, 1. 4 Compare and Order Integers The table shows the lowest elevation for several continents. Order the elevations from least to greatest. Do this on your own. Compare and Order Integers The table shows the lowest elevation for several continents. Order the elevations from least to greatest. -418, -156, -105, -86, -28, -12 Compare and Order Integers Marissa and her family are on a ski trip at Mt. Washington. They return from the slopes at 6PM. By 9PM the temperature had fallen 18˚ to the day’s low temperature of -8˚F. What was the temperature at 6PM? What are the facts? Compare and Order Integers Marissa and her family are on a ski trip at Mt. Washington. They return from the slopes at 6PM. By 9PM the temperature had fallen 18˚ to the day’s low temperature of -8˚F. What was the temperature at 6PM? What are the facts? - By 9PM the temperature had fallen 18˚ - The day’s low temperature was -8˚F. Compare and Order Integers Marissa and her family are on a ski trip at Mt. Washington. They return from the slopes at 6PM. By 9PM the temperature had fallen 18˚ to the day’s low temperature of -8˚F. What was the temperature at 6PM? What is the strategy to solve this problem? Compare and Order Integers Marissa and her family are on a ski trip at Mt. Washington. They return from the slopes at 6PM. By 9PM the temperature had fallen 18˚ to the day’s low temperature of -8˚F. What was the temperature at 6PM? What is the strategy to solve this problem? Work backward from the low temperature at 9PM to find the temperature at 6PM. Compare and Order Integers Marissa and her family are on a ski trip at Mt. Washington. They return from the slopes at 6PM. By 9PM the temperature had fallen 18˚ to the day’s low temperature of -8˚F. What was the temperature at 6PM? What is the temperature at 9PM? Compare and Order Integers Marissa and her family are on a ski trip at Mt. Washington. They return from the slopes at 6PM. By 9PM the temperature had fallen 18˚ to the day’s low temperature of -8˚F. What was the temperature at 6PM? What is the temperature at 9PM? -8˚ 9PM Compare and Order Integers Marissa and her family are on a ski trip at Mt. Washington. They return from the slopes at 6PM. By 9PM the temperature had fallen 18˚ to the day’s low temperature of -8˚F. What was the temperature at 6PM? How much higher was it at 6PM? 9PM Compare and Order Integers Marissa and her family are on a ski trip at Mt. Washington. They return from the slopes at 6PM. By 9PM the temperature had fallen 18˚ to the day’s low temperature of -8˚F. What was the temperature at 6PM? How much higher was it at 6PM? 18˚ 9PM 18 ˚ increase 6PM Compare and Order Integers The table shows the amount of time it takes Henry to do different activities before going to soccer practice. If he needs to be at practice at 8:15AM, what time should he wake up in the morning? Do this on your own. Compare and Order Integers The table shows the amount of time it takes Henry to do different activities before going to soccer practice. If he needs to be at practice at 8:15AM, what time should he wake up in the morning? 8:15AM Soccer practice 8:00AM Travel to Field 7:25AM Eat Breakfast 7:15AM Change into Uniform 6:55AM Check Email Compare and Order Integers The table shows the amount of time it takes Henry to do different activities before going to soccer practice. If he needs to be at practice at 8:15AM, what time should he wake up in the morning? Or you could have added the times in the table, 15 + 35 + 10 + 20 = 80 minutes Then figure out what time is 80 minutes before 8:15. 80 minutes is 1 hour and 2o minutes. An hour before 8:15AM is 7:15. 20 minutes before that is 6:55AM Compare and Order Integers How can symbols and absolute value help you order sets of integers?
