Negative and Positive Numbers and their Relationships By: Mr. Thiel

Positive Numbers Numbers that have a greater value than zero. Example: 3, 4 6 7 , 17.5, 32, 56, 187

Negative Numbers Numbers that have a smaller value than 0. Example: -0.32, -5, -13 3 4 , -81, -398

Zero Represents the value between negatives and positives. Example: Numbers Positive Numbers

Ordering Integers -5 -4 -3 -2 -1 1 2 3 When ordering integers, think about a number line. With negative numbers, the further away from zero you go, the smaller the number (the larger the negative, the smaller the value) Example: -5 -4 -3 -2 -1 1 2 3

Order the following numbers… From Least to Greatest -5, -8, 3, 5, -1, -9, 7, -3 -7 -6 -5 -4 -3 -2 -1 1 2 3 4 5 6 7 8

Order the following numbers… From Least to Greatest 77, -23, 55, 76, -13, -6, -8, -63, 12, -134 -70 -60 -50 -40 -30 -20 -10 10 20 30 40 50 60 70 80

Your Turn… Take the number you were given and get in order from least to greatest. There should be absolutely NO TALKING 
