Comparing Integers • The further a number is to the right on the number line, the greater it’s value. Ex: -3 ___ -1 < -5 -4 -3 -2 -1 0 1 2 3 4 5 . . -1 is on the right of -3, so it is the greatest.

Ordering Integers When ordering integers from least to greatest follow the order on the number line from left to right. Ex: 4, -5, 0, 2 -5 -4 -3 -2 -1 0 1 2 3 4 5 . . Least to greatest: -5, 0, 2, 4 . .

Ordering Integers When ordering integers from greatest to least follow the order on the number line from right to left. Ex: -4, 3, 0, -1 -5 -4 -3 -2 -1 0 1 2 3 4 5 . . . Greatest to least: 3, 0, -1, -4 .

Try This: a. -13 ___ 4 b. -4 ___ -7 c. -156 ___ 32 d. Order from least to greatest: 15, -9, -3, 5 ________ e. Order from greatest to least: -16, -7, -8, 2 ________
