Using Visual Manipulatives to Model Integer Operations

Using Visual Manipulatives to Model Integer Operations

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 :

Adding Integers............... 2 Simple Rules! I Saw the Sign!

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)
