Slide1Comparing and  Ordering   Whole Numbers Comparing  and  Ordering   Whole Numbers Comparing  and  Ordering   Whole Numbers Comparing  and  Ordering   Whole Numbers Example  1:   Compare  76  and  67 Example  1:   Compare  76  and  67 Write: Say: Write: Say: 67  <  76           67  is  less  than  76 67  <  76           67  is  less  than  76 76  >  67        76  is  greater  than  67 76  >  67        76  is  greater  than  67 Remember,  the  mouth  of  the  symbol  (>  or <)  always  opens  to  the  greater  number. Remember,  the  mouth  of  the  symbol  (>  or <)  always  opens  to  the  greater  number.

Slide2Example 2:  Blanca Peak is 14,345 feetabove 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 3 00 >  2 00 So 14,345 > 14,294

Slide3Caution!!!!!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 Incorrectly Lined Up Correctly  (at the ones place) 108,464 108,464 97,996  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

Slide4Let’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

Slide5Order the following numbers from greatest toleast. 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 6 1,565 7 1,649 7 5,367 70,000 > 60,000 So 61,565 is the least. 7 1 ,649 7 5 ,367 5,000 > 1,000 So 75,367 > 71,649 75,367 ; 71,649; 61,565  (greatest to least)

Slide6Let’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
