ab: Summary: An understanding of proof does not start in a high school geometry
course. Rather, attention to logical reasoning throughout a studentâ€™s
school experience can help the development of proof readiness. In the
spirit of problem solving, the author has begun to use some Japanese
logic puzzles other than sudoku to help students develop additional
problem-solving strategies while practicing deductive reasoning. When
students are confronted with a logic puzzle for which they have not yet
developed strategies for finding a solution, they are forced to put
their deductive thinking skills into practice. In this article, the
author highlights a few of the puzzle types that are less well known
(at least in the United States) and the proof-readiness skills they
help develop. He concludes that when students learn to provide
deductive arguments for their puzzle-solving strategies, they are
laying the foundation for good mathematical practicesâ€’in proofs and
beyond. (Contains 8 figures and 5 online resources.) (ERIC)
