Though I have to admit I'm rather confused by the mathematics of fractals there are numerous ways to incorporate this topic into my world history and world cultures classrooms.  For example, students can examine diagrams and/or arial photographs of Ashanti communities for patterns.  Then, we can discuss the structure as a means of supporting and reinforcing social hierarchy and structure.  We could also utilize Kente cloth as a tool for uncovering patterns across cultures and the diffusion of these patterns via the African diaspora.  Ultimately, these tools could be used in conjunction with sources regarding the diversity of African cultures, the complexity of African languages, and the expansive and diverse history of Africa to help students to better understand the people and continent.
