Using KenKen to Build Reasoning Skills
Reiter, Harold B.; Thornton, John; Vennebush, G. Patrick
Mathematics Teacher, v107 n5 p341-347 Dec 2013
KenKen® is the new Sudoku. Like Sudoku, KenKen requires extensive use of logical reasoning. Unlike Sudoku, KenKen requires significant reasoning with numbers and operations and helps develop number sense. The creator of KenKen puzzles, Tetsuya Miyamoto, believed that "if you give children good learning materials, they will think and learn and grow on their own" (Nextoy 2012). KenKen puzzles help develop perseverance and stamina, and in the classroom they promote problem solving, reasoning, and communication. Because KenKen puzzles can vary in difficulty, they can be used effectively in middle school classrooms, high school classrooms, extracurricular math clubs, mathematics courses for nonmajors, and methods courses for preservice teachers.
