在《数学课程标准》中提出:“数学学习应当是现实的、有意义的、富有挑战性的,有利于学生主动地进行观察、实验、猜测、验证、推理与交流等数学活动。动手实践、自主探索与合作交流是学生学习数学的重要方式。”猜想是根据不明显的线索或凭想象来寻找正确的解答思维活动,数学猜想是人们依据已有数学知识和经验,运用非逻辑的思维方法,凭借直觉而作出的假设和预测。培养小学生的猜想能力,不仅能够调动学生学习的积极性、主动性,而
Put forward in mathematics curriculum standard: “Mathematical learning should be realistic, meaningful and challenging, which is conducive to students taking the initiative to observe, experiment, guess, verify, reason and exchange mathematics activities. , Exploration and cooperation and exchange of students is an important way for students to learn mathematics. ”" Conjecture is based on obvious clues or imagination to find the correct solution to thinking activities, mathematical conjecture is that people based on existing mathematical knowledge and experience, the use of non-logical Ways to think, assumptions and predictions made with intuition. Training primary school students’ ability to guess not only can arouse the enthusiasm and initiative of students, but also
