About Me
I’m Mr. Hehn, and I’ve developed some excellent materials for my classroom throughout my 7 years as an elementary public school teacher that I’d love to share with you. I like to incorporate dancing, singing, and listening to music into my lessons. My project, NUMBEROCK, is a collection of music videos that teach/reinforce elementary school level mathematical concepts and primary grade numeracy to make learning math fun in a whole new way.

LYRICS

Isosceles triangles have two equal sides
like this mountain we’re about to climb;

and since one angle’s over ninety degrees,
an obtuse triangle is what we see.

If you add up every angle,
there are one hundred eighty degrees in a triangle.

If the length is equal on every side,
we say it’s equilateral, like this road sign;

and since every angle’s less than 90 degrees,
an acute triangle it will also be.

If skateboard ramps are your scene,
with three different sides they’re called scalene.

That triangle would also be called right
if a ninety degree angle is inside.

There are two ways to classify triangles:
by their sides and their angles,

like sails out on the high seas
can be right or isosceles.

Or look at the foot of this goose;
it’s scalene and obtuse.

When you break pool balls with a cue,
they’re equilateral and acute.
