数感,是一种主动地、自觉地或自动化地理解数学和应用数学的态度和意识。数感强的人能用数学的眼光去观察现实,能以数学的思维研究现实,能用数学的方法解决实际问题。一句话,数感是关系到人拥有的数学知识是“活”的还是“死”的。《数学课程标准》首次明确地把数感作为数学学习的内容提出来,可见培养学生数感的重要性。在小学数学教学过程中,我们经常会发现这样的现象:一个能考出“好分数”的同学在面对现实的问题情境时却不知该如何下手。如何拨开云雾见天日,让数感走向学生,使学生学会用数
Sense of number, is a kind of initiative, consciously or automatically understand math and applied mathematics attitude and awareness. Strong sense of the number of people can use mathematics to observe the reality of the vision, to study the reality of mathematical thinking, mathematical methods can be used to solve practical problems. In short, the sense of number is related to the mathematical knowledge that people have “alive” or “dead”. For the first time, “Mathematical Curriculum Standard” put the number sense as the content of mathematics learning, which shows the importance of cultivating students’ sense of number. In the process of elementary mathematics teaching, we often find such a phenomenon: a student who can test out “good grades” does not know how to start when faced with the actual problem situation. How to get rid of the clouds to see the sun, so that a sense of the number of students, so that students learn to use the number
