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

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

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

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

5. 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

6. 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

7. 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

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