Education conferences are always hit-or-miss affairs, but I had a good and productive time at the #NCTM Annual meeting this past week, thanks in part to @dodecahedra's excellent workshop on the geometry of polar curves. As he says, respect the shapes!
I was also really happy to finally meet him and @KarenCampe both in person for the first time, which swung the balance of my conference experience past the "worth it" threshold.
