The Mathematician Leonhard Euler proposed that all convex polyhedrons followed a simple rule: Vertices + Faces - Edges = 2.
In this investigation, children build a series of regular polyhedrons and use them to test Euler’s hypothesis.
The bundle includes nets for the first five regular polyhedrons and and investigation sheet, explaining the hypothesis and providing a table for children to enter their results and space to record their conclusion.
