 Explore the Beauty of the Golden Ratio

The Pentram is a special set of wooden shapes invented by Emil Simeonov that can be used to extend mathematical knowledge beyond that of the well-known Tangram shapes. The Pentram is based on a regular pentagon, and its pieces correspond exactly to the golden ratio leading to important mathematical discoveries and the forming of aesthetic images.

Both children and adults can use the multi-level cards as inspiration and, in the classroom, teachers can develop and support mathematical understanding using this innovative set of shapes.
