Many have heard of Kenko. It is the invention of a Japanese math teacher named Tetsuya Miyamoto, who says: "I believe that while the children are learning material, to think and learn and grow on their own." Imagine that!
Kenko is a brilliant puzzle that is the logic of Sudoku puzzles, and adds the use of basic arithmetic to Kenka a truly fascinating challenge on many levels.
But you do not have to be an ace to play Kenko mathematics. The rules are really easy to learn. A typical network consists of 16 squares, with four rows and four columns. Just as in Sudoku, you must use the digits from one to four in each row and each column. Can not repeat a digit in a row or column.
Kenko has a feature that some of the groups are limited by a bold border. Within these squares is a number, for example, 6, and sign a mathematical operation, for example, a plus sign (+). This only means that the digits in the squares must add the number 6.
If you want the number 15 with a multiplication (x) sign next to it in two places lined in bold, you know the digits in those places will be increased to 15.
Simple enough? Yes it is – even for a second grade can start making Kenko puzzle. That’s how easy it is to get started. However, the level of game can get harder – much harder.
Kenko can be played on grids of 6×6 squares, or 8×8 or 9×9 squares.
Completion of the 81 cells in a 9×9 grid can take hours or days. Or more! Once you start, however, find time to do Kenko. You will not be able to stop! Your mind will learn both logic and arithmetic, not even noticed.
Kenko is possibly the best year that the brain can never try. That’s why we need you to try. If you are a parent or a teacher, Kenko could become the greatest tool in your toolbox for educating your child or students interested in mathematics.
Kenko does not feel like math at all – is just pure fun
