Geometry students built their vocabulary words today. Polyhedrons are constructed with faces, edges and vertices. Our clay and toothpicks were a little messy, but a lot creative. In the pictures you can see tetrahedrons, pentahedrons, hexahedrons, heptahedrons and octahedrons. Most examples include two models of each polyhedron.
Inductive reasoning allows us to look at the data, find a pattern and make a generalization about that pattern. Students put their heads together to discover Euler’s Formula: V + F – E = 2. That is read “vertices plus faces minus edges equals 2”.
Once again, learning can get loud!
By the way, here is our riddle for the day: What did the bird do when he got scared? Poly he’d run! (Get it? Polyhedron!)
