After watching enough people work on sudoku number puzzles, it occurred to me that this logic game can be easily adapted to art by substituting the numbers for colors or symbols.
Color sudoku follows three basic rules:
1. Use all the color options in each box without repeating
2 Use all the color options in each row without repeating
3. Use all the color options in each column without repeating
Since I love sharing – feel free to download the low-tech color version of sudoku that I created as an extension activity. I printed mine on tag board and laminated to keep clean. I also wanted to keep the colors consistent between the game boards and the pieces so I printed out color sheets and cut them down into pieces that fit each puzzle. Since the 4 color sudoku need larger pieces than the 6 color and 9 color, I keep those pieces separate in a zip lock bag. Reuse a shallow class-pack type box to store the entire kit together.
Use the 4-color sudoku for younger students or to introduce the concept for the first time. Let the kids differentiate their own learning by choosing their own difficulty level. I don’t use answer keys (if you follow the rules, you know when you have found the solution) – although you could easily create your own by writing in the color names on an extra printout by solving yourself (or have a student do it for you).

Idea update 3/18/10: Print out duplicate sudoku game cards so students can challenge each other to see who can finish card first.
