数感是对数的一种感悟,它是一个人的基本的数学素养。由此可见,培养学生的数感就显得尤为重要,但数感的形成是一个逐渐积累和发展的过程,在新课程标准下如何在小学数学教学中培养学生的数感呢?我认为有以下几种途径:1联系生活实际,培养学生的数感第一学段是培养学生数感的重要时期,对于三年级学生来讲,他们已经具备了一定的生活经验,对较大的数也已经有了初步的感知,在教学第一单元《生活中的大数》时,我就在课前设计了一个小调研:1、调查一下家里的电器的价格并记录下来。2、感受一下自己走1000步大概有多远。3、数出1000粒大米,感受
Sense of number is a perception of the logarithm, it is a basic mathematical literacy. Therefore, it is very important to cultivate the sense of number of students. However, the formation of number sense is a process of gradual accumulation and development. How to cultivate the sense of number of students in primary school mathematics teaching under the new curriculum standard? Several ways: 1 contact with the actual life, to develop a sense of the number of students The first semester is to cultivate a sense of the number of students an important period for the third grade students, they already have some experience of life, the larger the number has also been With the initial perception, when teaching Unit 1, “The Biggest Number in Life,” I designed a small study before class: 1. Investigate the price of home electronics and record it. 2, feel about walking 1000 steps about how far. 3, count out 1000 grains of rice, feel
