Sierpinski's Triangle: Teaching Fractal Geometry to Kids
Learning about fractals with your students can be made easy when chunked into little pieces of information. Easily put, fractals are self similar patterns that can be found in many places, but nature is a great place to start looking. I put together a short presentation showing connections between fractals and nature here Fractal Geometry for Kids.
I also use the web site Fractalfoundation.org for videos and student made fractal art. Don't miss the fractivities page, however in my experience, the 3D Sierpinki Triangle is best made with 5th graders and up.
I conclude my presentation with this video from fractalfoundation.org
The art+math activity I used for 2nd grade through 5th grade was Sierpinki's Triangle, named after the Polish mathematician Waclaw Sierpinski, although it had been used in decorations for years. We colored in each step on the way to the finished product, keeping confusion to a minimum.
