长期以来,我们一直过多地强调数学的严谨性和科学性,而忽视学生猜想能力的培养,出现了学生想像力与创造力欠佳的现象。因此,在数学教学中要注意培养学生的猜想能力。牛顿曾指出:“没有大胆的猜想,就做不出伟大的发明。”在小学数学课堂教学中,运用猜想可以营造学习氛围, For a long time, we have been placing too much emphasis on the rigor and science of mathematics while ignoring the cultivation of students’ ability to guess, resulting in a phenomenon of poor imagination and creativity. Therefore, in mathematics teaching should pay attention to develop students’ ability to guess. Newton once pointed out: “Without bold conjecture, we can not make a great invention.” In the elementary mathematics classroom teaching, the use of conjecture can create a learning atmosphere,
