Reflection: Diverse Entry Points Factoring Completely - Section 3: Create a Diagram


The chart activity in this lesson is a great formative assessment on factoring.  Students need to understand the separate methods of factoring well enough to be able to categorize and represent them in a visual model.  I walked around and got a good idea of where each student was by looking at their charts (or occasionally lack thereof).   By discussing them in groups and choosing their favorite, this enabled students to improve their model.  Here is an example of a nice Sample Chart

I also use the chart to help the students focus their thinking as they are faced with factoring polynomials completely.  In past years, I have seen so many students freeze over what type of factoring to use for a given problem.  The chart can provide some extra support until they are confident enough not to need it any more.
