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:

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

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

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

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”!

Pick the Correct Symbol!
