To Gesture or Not to Gesture?

I'm preparing to teach my 7th grade students classification.  We usually use a mnemonic device to remember the levels of classification, and I wondered if I would still use gestures for this information.  I came across this great WB video posted below and my question was answered.  Of course I would still use gestures!

 I will be sure to post my students using Mirror and Teach-Ok after our work.  Unfortunately, it will be a few weeks.  My students are in engineering for the next 3 weeks and there in no WB learning taking place there.  Today, I actually cried because I miss my students and our WB learning. 

Anyway, check out the cool math video below. B
