The "Calcudoku" math puzzle (www.calcudoku.org) is great for teaching kids numeracy and logic reasoning. It is like Sudoku, but with addition, subtraction, etc., which makes for a much more interesting and fun puzzle.
My campaign has two main goals:
1. To get many more people solving Calcudoku puzzles
Calcudoku puzzles are fun, interesting, and exercise your brain. They're great as a teaching tool, or (if school was a while ago for you) to stay sharp with numbers.
Getting more people puzzling may involve some online advertising.
I'd also love to supply puzzles to print publications.
2. To develop new puzzle varieties
Puzzlers at http://www.calcudoku.org have already suggested more than 20 possible variations (for example, adding fractions, sums of squares, Fibonacci numbers, etc. etc.). I'd love to spend more time on developing these.
In any case, thanks for your support, no matter how small :-)
Try the puzzle yourself at http://www.calcudoku.org
It is also available in the Chrome Web Store.
