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

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

3. 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?

4. 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

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

6. 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

7. 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

8. 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

9. 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

10. ,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
