In this recording, I will demonstrate how to use the model described in the previous recording using black and red chips instead of Algebra tiles.
After watching the screen recorded demonstration, follow this link :

to the NVLM website and scroll down to "Color Chips Addition" and play with the virtual manipulative yourself.
Go to the NVLM website and scroll down through the virtual manipulatives until you see Color Chip Addition. Click and practice using the model to solve problems.
Adding Integers ……2 simple rules
Same signs:
- add the absolute value example: -2 + (-5) = -7
- keep the common sign 10 + 11 = 21
Different signs: example: -6 + 2 = -4
- subtract the absolute values ( 6 - 2 = 4 and it is -4 because
- keep the sign of the number -6 has a higher absolute value)
