Integers
6.3
So what is an integer?
Set of whole numbers (this includes zero)
and their opposites
{…-3,-2,-1, 0, 1, 2, 3…}
An integer and its opposite are the
same distance from zero on a number
line
The opposite of -4 is 4… both are 4 spaces
from zero
Positive Integers are…
greater than zero.
Negative Integers are…
less than zero.
Zero is…
an integer that is neither
positive nor negative!
Zero does not have an opposite!
Is that number an integer?
Absolute Value is…
number is the distance of a number from
zero on the number line regardless of
direction.
Absolute value is represent by the absolute value bars
EX:
6  6
6 6
Ordering Integers
When ordering integers, smaller numbers are always
to the left of larger numbers on the number line.
The further left a number is on the number line,
the smaller the number!
Quick Vocabulary:
Ascending- least to greatest
Descending- greatest to least
EX: -15 is smaller than -5 because -15 is to the left of -5!
Click the right answer!
Which number is the smallest?
Which set is ordered from least to greatest?

Another way to remember…
< This looks this
.
The arrow points to the smallest number!
If arrow tip points left…you say “less than”!
> This looks this
Remember:The arrow points
.
to the smallest number!
If arrow tip points right…you say “greater than”!
