Integers 6.3

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

4
Positive Integers are… greater than zero. Negative Integers are… less than zero.

5
Zero is… an integer that is neither positive nor negative! Zero does not have an opposite!

6
Is that number an integer?

7
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:

8
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! EX: -15 is smaller than -5 because -15 is to the left of -5! Quick Vocabulary: Ascending- least to greatest Descending- greatest to least

9
Click the right answer! Which number is the smallest? Which set is ordered from least to greatest?

10
Comparing Integers You see the small part 1 st ! You see the largest part 1 st ! I always eat the largest number!

11
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”!
