## Reflection: Modeling Expanded Notation for Dividing Hundreds - Section 2: Concept development

This was a good lesson that my students really enjoyed.  I heard almost from the beginning of the lesson, "Can we try one on our own?"  This is always a great feeling as an educator when students are comfortable telling me that they think they can do it with out me. I then get to sit back and watch and observe them show and communicate to me what they know.

As you can see in my reflection video, I had some fun surprising outcomes as students choose the problems they solved.  I'm looking forward to tomorrows lesson as we expand this method to include four digit dividends.
