## Reflection: Developing a Conceptual Understanding Two Digit Numbers: Even or Odd? - Section 2: Introduction to New Material

In years past, I might have simply told students "when you are trying to find out whether a two-digit number is even or odd, just look at the ones place."  However, now as I am working to help my students gain a deeper conceptual understanding (MP7), I push students to determine this rule on their own (MP1). I also encourage students to be able to explain WHY this rule exists instead of just memorizing a new "trick".  Additionally, for students who are struggling to understand, they will walk away with a greater conceptual understanding regardless because they will be able to hear their classmates struggle to identify this rule.  It is okay for students to think hard and struggle and it's okay for some of them to walk away still working to grasp the conversation during the independent practice.  These deep, meaningful conversations help students to deeply internalize the concepts and to gain new strategies for solving problems and thinking about numbers.
