Singing the quadratic formula!

Here is a novel approach along the lines of "teaching to learn".

Stick Man sings the quadratic formula.

Disturbing, yet at the same time potentially effective.

Spread the word.


Update for Profgrrrrl:
It may not be a bouncing ball, but the "Quadratic Rap" includes a visual aid. It is also superior to some of the other quadratic formula videos out there in that it says "all over 2a" rather than just "over 2a". Distributing the division is an important detail.

There is also a trigonometry interpretative dance. Clearly there are a lot of HS students using their cell phones to record video during math class and, based on this Graph Dance, there is some cult of trig teachers who "dance" the graphs of various trig functions. [I see the sine, cosine, tangent, and secant being illustrated in a rather extreme version of active learning.]

It needs the lyrics with the bouncy ball over it :)
