1. Warm Up
Use <, > or = to complete each statement:
-6…… …… ……...|5| |10|……...|-10| |9|……...|-2| |-8|……...|10|

2. Adding Integers

3. Let black blocks represent positive numbers.4
 7
 2 

4. Let red blocks represent negative numbers. -5  -1  -6 

5. Adding Same Sign Integers
When you add integers of the same sign, the sum also has that sign = 6  +  = 

6. Adding Same Sign Integers
When you add integers of the same sign, the sum also has that sign = -8  +  = 

7. Try some! Find the sum of the following:
7 + 4

8. When you combine blocks with opposite signs, they cancel each other out. 4 + -9 + 
= -5

9. You try! Add the following:
6 + (-4)  + 

10. Let’s practice! 5 + (-11) (-8) + 13 (-3) + 7 (-4) + (-5) + 15 6 + (-4)
Add the following integers, using blocks if needed.
5 + (-11)
(-8) + 13
(-3) + 7
(-4) + (-5) + 15
6 + (-4)
