Fractal Cutout Card Fractals are SMART: Science, Math & Art! www.FractalFoundation.org Copyright 2015 Fractal Foundation, all rights reserved 1 Overview Students will make a 3-dimensional fractal cutout card by repeating a simple process of cutting and folding. They can turn their cutout into a fractal popup greeting card, decorate it artistically, and share the lessons of fractals with others. Although it is formed by a very different process, the resulting fractal shares much in common with the Sierpinski triangle fractal. Appropriate for: grades K – 12, college and adults Objectives To gain skills in measuring, cutting and precision To gain experience in understanding that repeating a simple processes over and over can create a complex object To draw and identify lines and angles and classify shapes by properties of their lines and angles To experience ratio and portion in action To create and understand complex patterns in math To express creativity in connection with math To model with math and classify shapes by properties of their lines and angles To look for and make use of structure Materials 8.5” x 11” white paper 8.5” x 11” card stock in contrasting color Scissors Glue stick Rulers in centimeters (cm) Cutout Card worksheet
