## Reflection: Diverse Entry Points Mathematical Modeling: Linear Functions - Section 4: Modeling Linear Functions

I wanted to share a great method for finding slope that I have been using for several years.  These students have seen slope multiple times which means it should be mastered, but there are always students who need some review.   I set the information in a chart as seen in these Student Notes.  We then look at the change is y as x increases one unit.  There are many students who have struggled in the past with slope who get that Aha moment here.  To be honest, this is a visual, intuitive version of the traditional slope formula.  This is a very effective technique with both contextual and purely mathematical problems. Sometimes all it takes to filling holes is a conceptual approach.
