Comparing and Ordering Integers

  1. 1. Comparing and Ordering Integers Mrs. Young EMC 1
  2. 2. Before we begin… <ul><li>Let’s review!!! </li></ul><ul><ul><li>Which of the following are integers??? </li></ul></ul>-78 0 34 0.9 -2 -99 9,124 -7.2 -78
  3. 3. Place these integers on the number line… 0, -6, 3, -8, +1
  4. 4. Comparing Integers <ul><li>In golf, scores are related to a number of strokes called par. A score of 1 under par is represented as –1. A score of 2 over par would be written as 2. </li></ul><ul><li>Suppose you have a score of 2 over par and your friend has a score of 1 under par. Who has the lower score??? </li></ul>
  5. 5. Use the number line! <ul><li>Plot the integers on the number line. </li></ul><ul><ul><li>Remember, negative integers are to the left of 0, and positive integers are to the right of 0. </li></ul></ul>
  6. 6. Compare -1 and 2 <ul><li>When comparing two numbers on a number line, the number on the LEFT is the smaller number. </li></ul><ul><ul><li>Therefore, -1 < 2 OR we could say that 2 > -1 </li></ul></ul>
  7. 7. Compare the following pair of integers using > or <… <ul><li>0 and –10 </li></ul><ul><li>-9 and -5 </li></ul><ul><li>-4 and +4 </li></ul><ul><li>-7 and -1 </li></ul>
  8. 8. Ordering Integers <ul><li>You can order a list of integers from least to greatest or greatest to least. </li></ul><ul><li>Let’s order the following numbers from least to greatest: </li></ul><ul><li>-8, 34, -3, 0, 12, 19, 10 </li></ul><ul><li>Remember, the number that is on the far left is the least or smallest, and the number on the far right is the greatest. </li></ul>
  9. 9. You Try It! <ul><li>Order each set of integers from least to greatest : </li></ul><ul><li>12, -3, -8, 0, -1, 7 </li></ul><ul><li>-21, -9, -15, -33, -1 </li></ul><ul><li>-89, -77, 1, -45, 0, -100, -5 </li></ul>
