Flake Maker

Place in mathematics curriculum:

• Practice students' pattern recognition skills
• Practice students' plane geometry skills
• Illustrate the ideas of self-similarity and recursion
• Demonstrate fractal objects

This activity allows the user to generate interesting, irregular fractals. This activity would work well in mixed ability groups of two or three for about twenty-five to thirty minutes if you use the exploration questions and fifteen minutes otherwise.

Preparations for this activity:

• Give implicit directions on what they are to do. For example, "Today we are going to discover how to make fractals using ..."
• Discuss fractions and symmetry.
