This is a SMART Notebook file. It supplements the NYS EngageNY lesson 6 for Module 4 (Draw row and columns to determine the area of a rectangle given an incomplete array.)
This set of lesson slides are based on the materials available free of charge from New York State's engageny website at http://www.engageny.org/resource/grade-3-mathematics.
The slides are meant as a companion to the lesson module script and are meant to save other teachers having to make slides. I make no claim to the material content and believe my production of slides is fair use and non-infringing.
