Mrs. Starla Jones and Mrs. Tracy Baines’ Algebraic Connections collaborative class discovers polyhedron patterns. The students created hexahedrons, tetrahedrons, octahedrons, dodecahedrons and Icosahedrons. This hands-on project engaged the students in learning patterns associated with calculating the number of edges, vertices, and faces of each polyhedron. The students discovered several patterns and developed formulas to represent the patterns they discovered. The students also discovered if they count the number of faces, vertices, and edges of a polyhedron it can be placed in formula form. They found that the number of faces plus the number of vertices minus the number of edges equals 2. This F + V – E = 2 is known as the Polyhedral Formula or Euler’s Formula. They also were able to have fun with math!
