Using Sudoku to Introduce Proof Techniques
Snyder, Brian A.
PRIMUS, v20 n5 p383-391 2010
In this article we show how the Sudoku puzzle and the three simple rules determining its solution can be used as an introduction to proof-based mathematics. In the completion of the puzzle, students can construct multi-step solutions that involve sequencing of steps, use methods such as backtracking and proof by cases, and proof by contradiction to prove a theorem--that is, a solution of the Sudoku--to develop logical reasoning and clarity of writing. (Contains 12 figures.)
