Number Lines
Writing numbers on a number line makes it easy to tell which numbers are
bigger or smaller.
Negative numbers (-)
numbers below zero
Positive numbers (+)
numbers above zero
The line continues FOREVER in both directions
Numbers on the left are smaller than numbers on the right.
Examples:



5 is smaller than 8
-1 is smaller than 2
-8 is smaller than -5
An Example
John owes $3, Virginia owes $5, but Alex doesn’t owe anything, in fact he has
$3 in his pocket. Place these people on the number line to find who is poorest
and who is richest.
Having money is positive.
Owing money is negative.
So John has -3, Virginia -5, and Alex +3
Now it is easy to see that Virginia is poorer than John (-5 is less than -3) and
John is poorer than Alex (-3 is smaller than 3), and Alex is the richest (3 is
greater than -3 and -5).
