《数学课程标准》提出“数学的发展是一个充满着观察、实验、归纳、类比和猜测的探索过程。”猜想是展开数学思维过程的重要方法,它是建立在已有的事实经验基础上,运用非逻辑手段而得到的一种假设,是一种合理推理。纵观数学发展历史,很多著名的数学结论都是从猜想开始的。伟大的数学家高斯指出:“若无某种大胆放肆 The Mathematics Curriculum Standard states that ”the development of mathematics is an exploration process full of observations, experiments, inductions, analogies and guesses.“ ”Conjecture is an important way to start a mathematical thinking process and is based on the existing factual experience foundation On the use of non-logical means to get a hypothesis is a reasonable reasoning. Throughout the history of mathematical development, many well-known mathematical conclusions are from the guess. The great mathematician Gauss pointed out: "Without some bold presumptuousness
