Navigating the Path to Personalized Education
Many students do not have ... prism. The math software program they are using allows the groups to click on the prism and watch the colored images folding and unfolding in three dimensions, helping the students determine the number of faces, vertices, and ...
Spatial reasoning quiz
How many combinations are lost if 2 faces are un-colored? Does it make a difference if the 2 are adjacent, or opposite faces? Now I need to know if I can make a triangle that has interchangeable edges and vertices (I can swap the vertices for edges ...
Get out your crayons: it’s graph coloring time!
The face coloring problem assigns colors to the *faces ... have a graph G. The number of edges in the smallest cycle in G is called the *girth* of G. For any x,y≥2, there is a graph with girth x, and chromatic number y. What that means is that you can ...
The 11 Most Beautiful Mathematical Equations
Mathematical equations aren't just useful — many are quite beautiful ... sphere can be cut into four faces, six edges and four vertices. And we see that V – E + F = 2. Same holds for a pyramid with five faces — four triangular, and one square ...
The 17 Equations That Changed The Course Of History
Mathematics is all around us, and it has shaped our understanding of the world in countless ways. In 2013, mathematician and science author Ian Stewart published a book on 17 Equations ... vertices are its edges, and the polygons covering it are its faces.
