Mathematics Curriculum Standard for Ordinary Senior High School (Experiment) (hereinafter referred to as Curriculum Standard) is a programmatic document formulated by the Ministry of Education. This paper expounds the basic concept, design ideas, content standards and implementation suggestions (teaching, evaluation and textbook compilation). It is an important basis for the compilation of teaching materials, teaching organization, examination evaluation and the practical direction of curriculum reform. Under the framework of curriculum standards, there are several versions of "One Standard" at present: People's Education Edition A, People's Education Edition B, Jiangsu Education Edition, Beijing Normal University Edition, Hunan Education Edition, China Normal University Edition and so on. Different styles of compiling textbooks have different understanding of the direction of curriculum standards and the spirit of curriculum standards. At present, people's education edition A is adopted uniformly in most provinces. Under the framework of curriculum standards, other versions of teaching materials, such as Soviet education edition, are used for reference. By comparing the teaching materials, it is found that there are many differences and differences between the two teaching materials under "one standard and multiple editions". How to deal with it can only be based on the Curriculum Standard. Different versions of textbooks deal with some knowledge points slightly differently. Faced with this situation, it is definitely correct to adhere to the principle of "curriculum standards".
