While studying building solids with triangles, rectangles, pentagons, and hexagons, I tried to follow the Four Color Map Theorem and found that it worked for convex polyhedra. What is polyhedra? A polyhedron is a solid with flat faces (poly means many, and hedron means faces).

Four Color Map Theorem Creates New Branch of Mathematics: Graph Theory

Francis Guthrie, a 21 year old mathematics student at University College in London, was mapping the counties of England in 1852 when he noticed that he only needed four colors for the map.

Sports Field/Court/Rink Dimensions -- Architectural Drawings To Scale

After last week exploring the Major League Baseball Fields Dimensions, Outfield Square Footage and Homerun Distance, I received a lot of interest from the students to look at other sports fields dimensions.

Major League Baseball Fields Dimensions, Outfield Sq. Ft., and Homerun Distance

We had a very big week updating last week’s lesson on the probability of choosing the right teams in the NCAA tournaments:
