My sudoku creation for the December 2008 NRICH http://nrich.maths.org/public/viewer.php?obj_id=6368 is named \"Bochap Sudoku\" which illustrates the concepts of the four basic arithmetic operations.

To be more exact and accurate, all puzzles (including sudoku), interactive mathematical games and even board games can help in the teaching and learning of mathematics.


It is obvious that NRICH knows that puzzles and interactive mathematical games allow students to learn and play at the same time.

Beginning this month (November 2008), NRICH uses innovative flash interactivity for my sudoku creation (\"LCM Sudoku\") in http://nrich.maths.org/public/viewer.php?obj_id=6311

The variant illustrates the concept of Least Common Multiples.

My first version of \"LCM Sudoku\", using numbers and unknown variables, was posted on http://nrich.maths.org/public/viewer.php?obj_id=6018

To be more specific, that variant should be called \"Algebraic LCM Sudoku\".

I have posted a more challenging version of \"LCM Sudoku\", which uses advanced sudoku techniques, this month (November 2008) on the site http://www.chinasudoku.com/

For students who like fairy tales, they can try to solve another of my sudoku puzzle called \"Story Sudoku\".

My sudoku creation for the October 2008 edition of NRICH in http://nrich.maths.org/public/viewer.php?rss=1&obj_id=6310&part=index is the Addition Equation Sudoku.

ChiefKiasu:

That's an interesting twist to sudoku... using mathematical equations to seed the puzzle.

I appreciate the kind compliment from the Kiasu Chief.

Despite the general notion that no mathematics knowledge is required to solve a classic sudoku puzzle, sudoku can be used as a teaching aid in mathematics. I have contributed a sudoku puzzle to the August 2008 issue of NRICH.


The NRICH Project is based in both the University of Cambridge's Faculty of Education and the Centre for Mathematical Sciences. It is also part of the family of activities in the Millennium Mathematics Project.

My sudoku creation (\"Multiplication Equation Sudoku\") illustrates the concepts of multiplication and equations.
