Based on the development trend of international mathematics education and the excellent achievements of domestic mathematics education reform, the Standard puts forward many new viewpoints on the value of mathematics curriculum, mathematics learning objectives, mathematics learning process, teachers' teaching and evaluation. To sum up, it includes the following eight aspects: 1. It fully embodies the foundation, popularization and development of compulsory education; 2. It has changed the past curriculum system of primary school mathematics, which is oriented by knowledge accumulation, and established a curriculum system with the goal of building students' all-round, sustained and harmonious development; 3. Reorganized students' mathematics learning content; 4. The specific standards of mathematics curriculum are stipulated in sub-subjects; 5. Pay attention to the change of students' mathematics learning style; 6. Put forward the strategies that should be paid attention to in mathematics activities; 7. Reform the evaluation method and the purpose to be achieved; 8. Emphasize the application and influence of modern information technology in primary school mathematics education. The "Standard" has changed from the gradual adjustment of addition and subtraction knowledge in the Outline (Trial Revision) to the reorganization of primary school mathematics knowledge; Pay more attention to the cultivation of students' mathematics learning ability, emotion, attitude and method; From the syllabus (trial revision) to the emphasis on imparting and inheriting knowledge to cultivating students' innovative spirit and practical ability, from the past to the process and development evaluation. Compared with "Outline" (revised version for trial implementation), "Standard" has the characteristics of new concept and high starting point, which will have a far-reaching impact on the reform and development of primary mathematics education in the new century.
