A Math teacher... teaching?

You can't miss the opportunity of watching this YouTube video in which a Math teacher does something quite unique. 

If you want to catch your students’ attention for a couple of minutes (maybe you want to wake them up in a Monday morning) this is a highly effective way to do it.

I won’t tell you what it’s all about because you have to watch it and see it for yourself.

Enough. Just ‘push to play’. ;)
