牛顿曾经说过:“没有大胆的猜想,就做不出大胆的发现。”数学猜想实际上是根据已有的事实运用非逻辑手段而得到的一种假定,是一种合理推理。数学猜想能缩短解决问题的时间,能获得数学发现的机会,能锻炼数学思维。《义务教育数学课程标准》要求:“学生应经历观察、实验、猜想、证明等数学活动,培养学生合情推理能力和初步的演绎推理能力。”因此,在小学数学教学中,运用猜想可以营造学习氛围,激起学生饱满的热情和积极的思 Newton once said: “Without bold conjecture, bold discoveries can not be made.” Mathematical conjecture is actually an assumption derived from the use of non-logical means of existing facts and is a reasonable reasoning. Mathematical conjecture can shorten the time to solve the problem, get the opportunity of mathematical discovery, can exercise mathematical thinking. The standard of compulsory education mathematics curriculum requires: “Students should experience mathematics activities such as observation, experiment, guess, proof and so on, so as to cultivate students’ ability of reasoning reasoning and preliminary deductive reasoning.” Therefore, in elementary mathematics teaching, Can create a learning atmosphere, aroused students full of enthusiasm and positive thinking
