With the trajectory of a measure,
A magic is performed
And in the walkthrough
Ennobles Mathematics.

Intertwined in Trigonometry
In building a geoplane,
Make use of geometry
The magic of your plan.

With a piece of wood
And a lot of nails in the hand,
Thoroughly with the aid of a mechanical pencil
A way of assimilating the contents through manipulation is constructed.

In a simple piece of paper
The dots mark your milestone;
Using a brush
Finishes the work the mathematician.
