Compare, Order, and Round Whole Numbers
Objective: Compare, order, and round whole numbers through hundred billions.

Comparing numbers When we compare we use terms such as: Less than <
Greater than > Equal to =

Comparing (Step 1) When you are comparing numbers you must line them up by place value. For example: 18,066,000 18,131,000 Are these two numbers lined up correctly?

Comparing (Step 2) Start from the left. Compare the digits until they are different. 18,066,000 18,131,000 The hundred thousands digits are different. 1 is greater than 0, so…… 18,131,000 > 18,066,000

Compare. Write >, <, or =.
1. 25,431 _ 25,661 Step 1: 25,431 25,661 Step 2: 25,431 < 25,661

Compare. Write >, <, or =.
2. 4,569,102 _ 4,570,000 (step 1) 4,569,102 4,570,000 (step 2) 4,569,102 4,569,102 < 4,570,000

Compare. Write >, <, or =.
3. 73,000 _ 9,995 (1) 73,000 9,995 73,000 > 9,995 4. 37,329,410 _ 38,000,116 37,329,410 38,000,116 37,329,410 < 38,000,116

Order each set of numbers from greatest to least
5. 43,055; 422,007; 42,007 (Step 1) Line up the numbers by place value. 43,055 422,007 42,007

Step 2 Start at the left. Compare digits. 43,055 422,007 42,007
422,007 is the greatest number. Continue comparing. 3 > 2 43,055 > 42,007

,007; 43,055; 42,007 You do #6. Greatest to least 6. 82,811,121; 82,935,661; 812,661 82,935,661; 82,811,121; 812,661
