Reflection: Discourse and Questioning Factoring GCF and Grouping - Section 2: Factoring with GCF Algebraically and Graphically

A key shift in the Common Core is providing students more opportunities to evaluate and discuss mathematics.  One method I use is to give students several solutions to a problem and have them do a think-pair-share on which solution is correct.  In this lesson, I was able to implement this with an additional practice problem for factoring with GCF.

This particular problem has a common Misunderstanding that plagues students which is factoring out an entire term from a polynomial.  So often students will just leave it off rather than writing a one in its place.  I had students look at these two solutions and then discuss their opinion with their partner.  The resulting class discussion brought out several ways to look at this problem and I felt like students were more aware of this issue than they would have been if I told them about it or even made them practice several examples.
