Reflection: Developing a Conceptual Understanding Polynomial Puzzles 1: Adding and Subtracting Polynomials - Section 2: Investigation: Puzzle


I was extremely impressed by how well students did with this activity.  I actually anticipated that students would use much more subtraction to fill in the missing boxes.  Instead, I heard students reasoning more algebraically.  They would say things like "If I have a 2x^2 as the answer and I am starting with a 4x^2, then I must need a -2x^2."  This type of thinking was pushing students far beyond a typical combining like terms problem.  In order to fill in the missing boxes, students had to have a much more conceptual understanding of the way to combine the terms in a polynomial expression.
