Day 40 – Many ways of proof

So I decided to talk with the students about proof.  Students are definitely challenged by the concept and this is going to be a long road.  To ease the road, I decided to introduce the two column version and flowchart version of the vertical angles proof.  I think that this is the beginning of paving of a long road.  The lesson ran a bit long and I decided to spend time on making sure the explanation was sound and did not spend time on a solid formative assessment.  I look forward to building on the concept.
