《义务教育数学课程标准》关于学习内容中有六个重要概念,即数感、符号感、空间观念、统计观念、应用意识、推理能力,数感摆在了首位,可见其重要性。培养学生的数感可以从以下三个方面入手:一是在生活情境中建立数感;二是在活动体验中发展数感;三是在比较估计中提升数感。 There are six important concepts in the compulsory education mathematics curriculum standard, that is, the sense of number, sense of symbol, concept of space, concept of statistics, sense of application, reasoning ability and number sense. To cultivate the sense of number of students can be started from the following three aspects: First, to establish a sense of number in the context of life; Second, to develop a sense of the number of activities in the experience; Third, to enhance the number of senses in the comparative estimate.
