Briefly describe the content structure of primary school mathematics curriculum in China stipulated in the standard.
Answer: The Mathematics Curriculum Standard for Full-time Compulsory Education (Experimental Draft) promulgated in 200 1 integrates the contents of the original syllabus and adds the contents of practice and comprehensive application. Generally, it is divided into four areas: number and algebra; Graphics and space; Statistics and probability; Practice and comprehensive application. From the content point of view, the nine-year compulsory education stage is designed as a whole and divided into three sections. The first and second phases are equivalent to the original primary school stage. The main features of the first and second phases are as follows: 1. Number and algebra. This part of the content is the integration of the original mathematics with the preliminary knowledge of calculation and algebra, which accounts for the largest proportion in the content of primary school mathematics curriculum. The second is space and graphics. This field is divided into four aspects: understanding of graphics; Measurement; Graphics and transformations, and graphics and positions. Pay attention to the common problems in students' life and introduce this part. The third is statistics and probability. This part focuses on cultivating students' statistical concept; Let students experience the process of processing data; Experience the possibilities in a specific situation. The fourth is practice and comprehensive application. The first stage focuses on practical activities. Design a situation closely related to students' life, where students can participate in activities, so that students can collect information, discuss in groups, ask questions and solve problems. The second period is comprehensive utilization. It is to enable students to understand the extensive relationship between mathematics and life through mathematical activities, learn to comprehensively apply the knowledge and methods they have learned to solve simple practical problems, deepen their understanding of what they have learned, acquire thinking methods for solving problems by using mathematics, and cooperate with others.
