Dave Hewitt's Video

I watched Dave Hewitt's video a long time ago. Today I tried, in vain, to look it up online through YouTube. Nonetheless, I shall embark on discussing the video and the ideas presented there.

One thing I still remember was the way he tapped with his stick on the board, and a little bit of theatricality (is that a word? yes, just checked it online), to have students understand the number line and the order of numbers. I think it was a good way because you can see the whole collective engaged at the same time in learning and showing to the teacher that they knew. It was also a non-intimidating way to give students who are falling behind an opportunity to catch up with the rest of their classmates. When they are responding to the teachers prompts is virtually impossible to realize who made a mistake, who didn't... etc. Also, when the collective made a mistake there was no visible students who could be ashamed or not even made to stand out.

Furthermore, the teacher found a seamless way to introduce a concept of unknown and of variable.
