First, the students drew several rectangles and then, among these constructions, they chose the ones that they found most harmonious.

After that, they read a short text explaining the divine proportion (or golden ration) and after calculating quotients, they identified golden rectangles in different artistic and architectural works. Was the previously chosen rectangle a real golden rectangle? Is an A4 size sheet a golden rectangle?

Finally, the students drew a golden rectangle and a golden spiral following very precise instructions.

Aims of the activity:

-learn about the golden ration, the way the divine proportion influenced ancient and modern architecture how it appears in some patterns in nature, including the spiral arrangement of leaves and other plant parts.

- improve mathematical skills.
