### 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)

108,464108,464

97,996 97,996

Note: When one whole number hasmore digits than the other, it is greater.

Write: 108,464 > 97,996 or 97,996 < 108,464

### 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

### Order the following numbers from greatest to least.61,565; 71,649; 75,367

75,367 ; 71,649; 61,565 (greatest to least)

### 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
