Mansour Ghaznavi

Mansour Ghaznavi has studied mathematics and mathematical patterns for many years. In 1982 he invented a mathematical puzzle, "Math-Go-Round," and received a patent for it. Mr. Ghaznavi studied and researched patterns in number systems, and after ten years of research developed Multiplication Plus™... Circus of Patterns, which is the world's largest mathematical learning chart. In 1994 Mr. Ghaznavi served as instructor of mathematics at the Center for Talented Youth at the Johns Hopkins University, where Mr. Robert Wells and other teachers have used his chart in Math Reasoning class during the summer program.

New Discoveries

In 2000 Mr. Ghaznavi developed four new mathematical charts: Fractions, Decimals, Sequences, and Discovery of Mathematical Activities. These charts are described on this web site and are available for purchase here.

As result of 25 years of research and study in mathematical patterns and relationships, Ghaznavi was able in 2005 to complete the development of three new mathematical charts in Algebra (coming soon). He is now working on a new chart, "Ghaznavi's Magic Chart," which will be out in 2006.
