Reflection: Flexibility Everyone Try It! (Equal & Opposite Change) - Section 1: Opener

 

A lesson like this requires that I'm very flexible in my approach and in how I listen because while there are certain paths that seem obvious to me, children find many different ways to reason through this algorithm.

I encourage flexible thinking in my students when we discuss how it's helpful learn alternative approaches. I explain that I'm teaching this method because I have seen in the past how it helps students develop a deeper understanding of addition and regrouping. 

My job as a teacher is to make sure they have enough information to make the choice, and that they give new methods a chance.  Once they have had enough practice with this method to achieve reasonable proficiency, they can choose their preferred way to solve any given equation.
