Talks at Google – KenKen©: Happiness Through Math

Tetsuya Miyamoto is a mathematics teacher and inventor of KenKen©, the world’s fastest growing logic and math puzzle. He shares his story behind the puzzle’s origins, outline his teaching philosophies, and teach viewers how to create their own puzzles! Miyamoto was working as a primary school math teacher when he devised the first-ever KenKen© in 2004. He sought to create a teaching tool that allowed his students to learn through independent thinking as opposed to rote instruction. KenKen© was to encourage his students to embrace creativity, deductive reasoning, ingenuity, and perseverance; it quickly erupted into the international puzzle craze we know today as it’s published in over 150 newspapers around the world.

To make children’s futures brighter with the puzzle in Thailand

I visited Chiang Rai, Thailand not only to introduce the puzzles to children but also help them make their own problems. I want to publish a book that is made of the puzzles by the kids and donate all the money from selling the book.  The children worked very hard with patience, trying to make their puzzles.
