Today, some students of the IES Francisco Montoya, from Las Norias (Almería) have constructed the 2nd iteration of the Menger sponge, with the help of their math teacher Lidia García. They have used 1056 squares, 176 squares per 6 colours, one for each face. They have spent about 3 hours to complete it. Really cool and funny!
This project, started with David Crespo as explained in this post, will be presented at the XII Feria de la Ciencia de Sevilla together with many other manipulative games with fractals.
You can see it these days in the hall of the school center!
