**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

11
Rounding!

12
**The rounding poem Find your number Look right next door**

4 or less, just ignore 5 or more add one more! Write this poem down in your notes!

13
**Round to the place value indicated by the underlined digit.**

545 500 ,256 783,256 783,000

14
9. 24,592,124 24,592,124 25,000,000 ,129,811 674,129,811 674,130,000
