Abstract
- The article presents several mathematical games related to ellipse. This game is tracing a perfect ellipse. One example is the two thumbtacks that stick in a sheet of paper, putting a loop of string around them and keep the string taut with the point of a pencil. Moving a pencil around the tacks will trace a perfect ellipse. Another method can be demonstrated with a circular cake pan and a cardboard disk having half the diameter of the pan.
