"Donald Duck in Mathmagic Land"

In this video we can see at first, Donald was not interested in exploring the world of mathematics (he think that mathematics was for "crazy"). However, when the "Lord Spirit" suggests a connection between mathematics and music, Donald begins to become intrigued.

Donald travels to Ancient Greece, where Pythagoras and his colleagues are discovering math's relationships. Pythagoras (playing the harp), a flutist, and a double bass player perform a "jam session", in which Donald intervenes by playing a vase as a bongo, because he wanted to put the group "rhythm". The music of Pythagoras, as explained by the Spirit, establishes the parameters of current music.

Then, Donald finds in his hand a pentagram, the symbol of the secret society of the Pythagoreans. The Spirit explains to Donald how the mysterious golden number appears on the pentagram. Then, it is evident that the pentagram contains a pattern to construct several times golden reflectors one on top of the other. According to the Spirit, the golden rectangle has influenced both ancient and contemporary cultures in various ways.

This video is really a good resource to use because it is a funny short. Therefore, it could be used even in any primary education course, even if it is simply an introductory activity.
