I love fractals. So what better way to celebrate winter than creating a fun card based on the famous Koch snowflake (also know as the Koch star or island). First described by Helge von Koch in 1904, the “self-symmetrical” geometric shape is based on an equilateral triangle. It’s a shape that can have infinite perimeter, but finite area. Cool right?
This project uses the Koch snowflake as a pop-up element in a standard card, useful for birthdays and other occasions (like World Math Day on March 1). It requires simple, common materials and doesn’t take much time to complete. It’s a great math project for kids too!
