Rock, Paper, Math

I have a group of wiggly third graders this year - my class is mostly boys with a few girls.  My principal has suggested using some brain breaks.  I would love to implement a few brain breaks that also involve some content review.  That is why I love this video with a version of rock, paper, scizzors that reviews multiplication facts (if you teach younger students I'm sure you could substitute with addition or subtraction instead).

This comes from a book entitled Energizing Brain Breaks.  You can find a few more free videos at the website here.

What brain breaks do you use?
