MATEMÁTICAS DE VERANO

El verano está para divertirse, y que mejor que hacerlo ¡jugando con Polifieltros 3D! Si además lo combinamos con Neotrie, el nuevo software de Realidad Virtual, que está desarrollando Virtual Dor, la Geometría toma una nueva dimensión, jamás experimentada hasta ahora.

Esta nueva experiencia es la que han vivido los chavales del Club Náutico de Aguadulce, en unas jornadas organizadas por Juega Conmigo Talleres, durante esta semana del 24 al 27 de octubre de 2017.

MENGER SPONGE WITH 3DPOLYFELT

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!

SQUARE BUILDINGS

How many squares do we need to build the 1st iteration of a Menger sponge? Children can easily count this, if they chose 6 different colors to make it, such that all squares looking at the same face have the same color. In the picture below, we see for instance that the yelow exterior face has 8 squares, and we have 4 more yelow squares in the interior. This gives12 squares per color, so times 6 gives 72 squares. For the second iteration we would need 1056 squares!! We will try to make it soon. If you are interested on a mathematical formula for this and the nth-iteration of the Menger sponge, please visit our blog Juegos Topológicos.

Here, we have pushed the corners to make this nice version with octogonal faces. The flexibility of this material allows to make new figures and shapes.

Mathematics is always fun with 3D Polyfelt, but children also like to play and make its own figures and constructions!

And you can make your own house to play with your dolls!

XIV CEAM MÁLAGA

Today we have held a special session with our 3D Polyfelt game in the "XIV Congreso de Enseñanza y Aprendizaje de las Matemáticas". This congress has been organized by the SAEM Thales, and it  has hosted more than 200 houndred math teachers of all levels. We have enjoyed a lot constructing many varied geometric figures. Thank you all for coming! (Read more to see more pictures)
