Vihart makes math concepts like rotational symmetry and prime factorization more fun.
BTW, I am not responsible for any lost productivity that may result from your engagement with this video ;-).
I say that because in my last parent teacher conference, my son’s teacher noted he was doodling all over his papers. I could have blamed it on his active imagination or his love of drawing. But truth is – it was my – I mean Josh Ming’s and Anna Wood’s fault. One day I saw their tweets on Vihart’s hexaflexagon video. The boys and I have been hooked on hexing and flexing and doodling like a mathematician ever since.
