You can use a number line to order numbers.
 A number line has its numbers written in order from least to greatest on a line.

When comparing two numbers,
you can use a  
greater than
(>) , less than (<), equal (=), or not equal sign

 to always read 
a number sentence from
left to right!

 

Using a number line to compare whole numbers

4,843 is to the right of 4,456 on the number line.  So 4,456 is less than 4,843.
4,456 < 4,843

Example 1:

Use the number line to help you compare the numbers 2,500 and 3,200.

3,200 is to the right of 2,500 on the number line.  So 2,500 is less than 3,200.
2,500 < 3,200

Example 2:

Use the number line to help you find which symbols will make the number sentence true. 

< ,
 
> ,
 
= ,
 

 

1,800  

          

 3,200

3,200 is to the right of 1,800 on the number line
So 1,800
is less than 3,200 and 1,800 is not equal to 3,200.

1,800

   <

3,200
1,800
 

 
3,200
 

 

Remember: A number line has its numbers in order from least to greatest on a line.
