Robert F. Griffin, Jr. (neo)

My goal is to provide Educators a supplemental means by which to instruct in some of the fundamentals of Mathematics such as Combinatorics, Number Theory, Graph Theory, etc. With several of these works, I am conveying directly the underlying numeric architectures of perfectly balanced mathematical fields as just one way to allow Students to learn about some of the aforementioned subjects directly through interactive play, emphasizing keen observation as well as pattern recognition... The Coloring Puzzles are designed to not only reinforce the fine motor skills required for putting pencil to paper, but reveal the number sequences of the "symmetric-weaving..." I am also publishing my Universal Game Board, which I am making available as Puzzles. One has a three-color 18x18 grid for Wordplay, and the other has a 9x9 grid for Sudoku-Match3, and then there are the Circ-32 boards. All are archetypal, making the exploration of new games possible as a potential creative exercise...
