What’s the Best Lesson You Taught This Year?

I know teachers work their tails off all the time, but, sometimes, the stars align and you have a near-perfect day, where the kids are on point, the prep was done just right, and everything runs smooth as silk. What was your best lesson/unit that you got to work on this year? 

I got to run some great workshops for teachers this year, one of which was Presenter Bootcamp. The first day was a disaster...traffic made me late, I had to figure some timing issues out, etc. It wasn't a BAD workshop, just not as good as I wanted it to be. But the SECOND time I ran it was insanely better. The content didn't change significantly, but everything else just worked out better.

It really showed me how it's the little things that go into a day that can really take a lesson from good to great. My content and pedagogy were already solid, but learning from my mistakes was able to help me pull together a much stronger mental picture of how the day SHOULD go.

So what worked for you this year and what contributed to its success?
