1 -1 Comparing and Ordering Whole Numbers Additional Example 1: Using Place Value to Compare Whole Numbers Belize’s 2000 population was 249, 183 people. Iceland’s 2000 population was 276, 365 people. Which country had more people? Start at the left and compare 249, 183 Belize digits in the same place value position. Look for the first 276, 365 Iceland place where the values are different. 40 thousand is less than 70 thousand. 249, 183 is less than 276, 365. Iceland had more people. Course 1

1 -1 Comparing and Ordering Whole Numbers Try This: Example 1 In 2000, the population of San Diego, California was 1, 223, 400 people. In 2000, the population of Dallas, Texas was 1, 188, 580 people. Which city had more people? Start at the left and compare 1, 223, 400 San Diego digits in the same place value position. Look for the first 1, 188, 580 Dallas place where the values are different. 200 thousand is greater than 100 thousand. 1, 223, 400 is greater than 1, 188, 580. San Diego had more people. Course 1

1 -1 Comparing and Ordering Whole Numbers To order numbers, you can compare them using place value and then write them in order from least to greatest. You can also graph the numbers on a number line. As you read the numbers from left to right, they will be ordered from least to greatest. Course 1

1 -1 Comparing and Ordering Whole Numbers Remember! < means “is less than. ” 3<5 120 < 504 > means “is greater than. ” 17 > 9 212 > 83 Course 1

1 -1 Comparing and Ordering Whole Numbers Additional Example 2: Using a Number Line to Order Whole Numbers Order the numbers from least to greatest: 675; 1, 044; 497 Graph the numbers on a number line: The number 675 is between 600 and 700. The number 1, 044 is between 1, 000 and 1, 100. The number 497 is between 400 and 500. 497 675 1, 044 400 600 800 1, 000 The numbers are ordered when you read the number line from left to right. The numbers in order from least to greatest are 497, 675, and 1, 044. Course 1

1 -1 Comparing and Ordering Whole Numbers Try This: Example 2 Order the numbers from least to greatest: 732; 923; 502 Graph the numbers on a number line: The number 732 is between 700 and 800. The number 923 is between 900 and 1, 000. The number 502 is between 500 and 600. 502 732 923 400 600 800 1, 000 The numbers are ordered when you read the number line from left to right. The numbers in order from least to greatest are 502, 732, and 923. Course 1
