WHAT ARE
INTEGERS?
Negative whole numbers and zero.
DEFINITION OF
INTEGERS
-3, -5, 0, 1, 7, and 18 are
integers.
1.6, ½, 5%, and -2.43 are
not integers.
Integers consist of all positive whole numbers

Imagine a straight line where each point represents a
number. This is called a number line.
INTEGERS ON A
NUMBER LINE
Fun Fact!
In a number line,
numbers are 
arranged from 
left to right in 
increasing order.
Negative numbers 
are on the left of 0. 
Positive numbers 
are on the right of 0. 
Zero is neither 
positive nor negative.
0 -1 -2 -3 -4 1 2 3 4 5

Locate the corresponding point to the left or to the right of 0.
Example: Plot 4 on the number line.
PLOTTING INTEGERS
ON A NUMBER LINE
Because 4 is positive, we plot 4 units to the right of 0.
0 -1 -2 -3 -4 1 2 3 4 5
