The fifth day of class began with an introduction of a guest speaker, Mike South. He began class by giving the job description of a mathematician. He then went on to explain Fractals to the students using the Koch Snowflake curve. Once students got an understanding of fractals they were each given a chance to create their own Fractals on graph paper. The class then had an comparative disscussion of each person's results.

Next each student had a chance to have the computer create a fractal using a rule that they create. After the break, Mike began class with a discussion about abstract algebra, specifically symmetry. Using 3D shapes, the students were able to identify symmetry in each shape. Using a triangle Mike had created, they were able to learn about different types of symmetry including rotational, line, and flip symmetry. They even filled out a table listing all the symmetry of a triangle and used the table to uncover patterns.
