Integer Models

R-56 Private Think Time: When you think about positive and negative numbers what models come to mind?

-Number lines
-Coordinates graph (positive and negative numbers)
-absolute value. Distance from zero. [-5] 5 units from zero
-regular graph

-receipts: extreme coouponers
-Test scores
