Reflection: Developing a Conceptual Understanding Sorting Polynomial Equations and Identities - Section 1: Warm up and Homework Review

I love how this lesson builds a deeper conceptual understanding of algebraic expressions (Math Practice 7).  I think often students lack a full understanding of the purpose of a variable.  Many don’t truly understand that a variable represents ALL possible numbers.  The whole purpose of this lesson is to build that understanding.  I was pleased with the results of the warm up which is a preview of the day’s lesson, kind of like the blurb on the back of a book.  There was some creative thinking occurring as  you can see in these samples of Student Work.  I really like how they used what they knew and came up some interesting ideas.  One student initially said that the expression was never true but then revised her answer as she thought about it some more.  Getting students to push their thinking to new places is the essence of the Common Core to me.
