On Sunday April 10, 2011, we built the world’s largest fractal triangle in the Albuquerque Convention Center. Almost 100 volunteers helped assemble the 192′ wide triangle – incredibly in just under 1 hour. Children from all over the world participated by creating triangles. See the full list of participating schools here.
This is a giant math project as well as a collaborative art project. The triangles are assembled in self-similar groups of three in the following sequence: 3, 9, 27, 81, 243, 729, 2187, 6561. One of the many math lessons people learn through this project is about exponents, and 6561 is 3 raised to the 8th power (3^8) or 3x3x3x3x3x3x3x3.
Many thanks to all the volunteers, all the children who made triangles, and to the Albuquerque Convention Center for graciously donating the exhibit hall for the Trianglethon!
