作为《数学课程标准》重要目标的数感,对于人的发展具有重要的意义和作用。数感的建立是提高学生数学素养的重要标志。培养学生的数感就是使学生学会用数学的眼光去有意识地观察、认识周围事物,从现实的情境中发现、提取数学问题;用数学的思维方法思考问题,有意识地将现实问题与数量关系建立联系;同时灵活地运用数的观点理解和解决现实问题。数感作为学生的一种基本
As a “mathematical curriculum standards,” an important sense of the number of goals for the development of people has an important significance and role. The establishment of number sense is an important symbol of improving students’ mathematical accomplishment. To cultivate the sense of number of students is to enable students to learn to use mathematical perspective to consciously observe and understand the surrounding things from the reality of the situation to find and extract mathematical problems; mathematical thinking thinking, consciously the relationship between the number of real problems and the establishment of Contact; at the same time flexible use of the number of points of view to understand and solve practical problems. Sense of number as a basic student
