新的《数学课程标准》关于学习内容一项中有这样的描述:在各个学段中,《标准》安排了“数与代数”“空间与图形”“统计与概率”“实践与综合应用”四个学习领域。课程内容的学习,强调学生的数学活动,发展学生的数感、符号感、空间观念、统计观念,以及应用意识与推理能力。数感主要表现在:理解数的意义;能用多种方法来表示数;能在具体的情境中把握数的相对大小关系;能用数来表达和交流信息;能为解决问题而选择适当的算法;能估计运算的结果,并对结果的合理性作出解释。
The new Mathematics Standards for Classroom contains a description of the content of the study: In each of the sections, the Standard arranges “numbers and algebra”, “space and graphics”, “statistics and probability” “Practice and integrated application ” four learning areas. Course content learning, emphasizing students’ mathematical activities, the development of students sense of the number of symbols, spatial concepts, statistical concepts, as well as the application of awareness and reasoning ability. Sense of number mainly in: the significance of understanding the number; can use a variety of ways to represent the number; can grasp the relative size of the relationship between the number of situations; can use the number to express and exchange information; can solve the problem and choose the appropriate Algorithm; be able to estimate the result of the operation, and explain the rationality of the result.
