1. Integers
6.3

2. 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

3. Positive Integers are…12 5
greater than zero.
1,234 7
Negative Integers are… -7
-12
-1,234 -5
less than zero.

4. Zero is… an integer that is neither positive nor negative!
Zero does not have an opposite!

6. 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

7. 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!

8. Click the right answer! -13 -23 8 20 -3 -15, -8, -3 0, -2, -4
Which number is the smallest?
-13
-23 8 20 -3
Which set is ordered from least to greatest?
-15, -8, -3
0, -2, -4

9. Comparing Integers < Less Than > Greater Than ≠ Not Equal to =
You see the small part 1st!
You see the largest part 1st!
<
Less Than
>
Greater Than
I always eat the largest number! ≠
Not Equal to =
Equal to

10. 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”!
