Comparing and Ordering Whole Numbers Example 1: Compare 76 and 67 Write:Say: 67 < 76 67 is less than 76 76 > 67 76 is greater than 67 Remember, the mouth of the symbol (> or or <) always opens to the greater number.

Example 2: Blanca Peak is 14,345 feet above sea level. Crestone Peak is 14,294 feet above sea level. Which peak is taller? 1. Line Up the place values by lining up the ones. 2. Begin at the left. Find the first place where the digits are different 3. Compare the value of the digits. 14,345 14,294 14,345 14,294 different same 300 > 200 So 14,345 > 14,294

3
Caution!!!!! Be sure to line up digits with the same place value when comparing or computing. Example: You score 108,464 points. Your friend scores 97,996. The higher score wins. Who wins? Lined Up IncorrectlyLined Up Correctly (at the ones place)108,464 97,996 Note: When one whole number has more digits than the other, it is greater. Write: 108,464 > 97,996 or 97,996 < 108,464

4
Let’s Try! Compare using, or =. 534 __ 509 45,943 __ 45,494 904,109,005 __ 940,109,005 174,903,845,182 __ 174,903,845,182

5
Order the following numbers from greatest to least. 61,565; 71,649; 75,367 1. Line up the numbers at the ones place. 2. Begin to compare at the left. 3. Continue. Find the first place where the digits are different. 61,565 71,649 75,367 61,565 71,649 75,367 70,000 > 60,000 So 61,565 is the least. 71,649 75,367 5,000 > 1,000 So 75,367 > 71,649 75,367 ; 71,649; 61,565 (greatest to least)

6
Let’s Try!! Order from least to greatest… 2,756,833; 2,756,820; 2,756,338 Order from greatest to least… 90,654; 87,223; 87,954; 90,556
