Adjustments to the Introduction

This introduction to the lesson is presented in a direct instruction way.  As I have started shifting to a more student led approach I have made some minor tweaks to how the examples begin.  Instead of telling students how to solve the problem while modeling it, I let them work on the problem by themselves.  After they have attempted to solve the problem on their own we can return to the given steps and see if they match the process used.
