Statement of Inquiry Simplifying quantities and understanding equivalent relationships between different forms of representations, can help me make logical decisions Spatial relationships are a means of understanding the physical and abstract world Relationships can be expressed in a generalized form whose rules are used to problem solve Linear relationships can model many situations and systems in
real life
Interpreting the inner meaning behind different forms of representation can help us in understanding relationships.
