This book has its roots in a previous publication of mine, Spherical Harmony: A Journey of Geometric Discovery. I will introduce the concept of spherical harmonics, but the main focus will be on... More > fractional harmonics and their associated polygram, or star polygon. There exists a unique fractional harmonic of each of the infinite number of star polygons.
Much has been written about the pentagram and the golden ratio that is embedded in its geometry. However, it was the heptagon and associated heptagram that really piqued my interest. So I decided to explore the heptagram since I didn't know much about its geometric properties or characteristics and there wasn't much written about them either. The prime number seven has a special place in the ancient world and was referred to as the virgin number and was the most sacred number in many religions. some amazing ratios of proportion.< Less
Students find sums of the measures of interior angles of polygons, sums of the measures of exterior angles of polygons, and measures of single angles in a regular polygon. They consider triangles,... More > quadrilaterals, pentagons, hexagons, heptagons, octagons, decagons, and dodecagons. They receive immediate feedback as their answers decode a secret message. The self-checking nature motivates students and reduces overhead for teachers. Teachers, please require the students to show all of their work.< Less
The following workbook offers a fun way to learn polygon shapes by playing the age-old game "squares" (only with a twist). Using isometric dots, students will compete against each other to... More > form various polygon figures by connecting dots. So much fun, they won’t even know their learning
