Christopher Danielson posts a video of Good Teaching:
My eyes tear up watching this sequence. I am neither kidding nor exaggerating. It gives me hope for quality classroom instruction in elementary mathematics. Be sure to notice the transition to a new task at the 4-minute mark, and how the teacher deals with the struggle that occurs at the 6-minute mark. Also please look in the kids’ eyes. Watch their body language and their waving hands. Watch them think.
You cannot flip the first instructional activity because it involves adapting instruction in response to student ideas, and it involves students justifying their thinking to the teacher and to each other.
You can’t flip that.
