Twenty-six mathematics textbooks for grades one to three have been compiled, including 5 compulsory books, 2 elective books/kloc-0 and 2 3 elective books. Each volume in this 10 volume contains a module. Take 3 parts and 6 volumes, 4 parts 10 volume, and each volume contains a special topic. According to the Mathematics Curriculum Standard for Ordinary Senior High Schools (Experiment) (hereinafter referred to as the Standard), each volume of1-kloc-0/0 has 36 class hours, and each volume of1-26 18 class hours. Compulsory course 1-5 ends from Grade One to Grade Two. The first volume is equivalent to the required module 1 in the standard, including set, function concept, exponential function, logarithmic function and power function. This volume is the basis of other volumes. The second volume is equivalent to the required module Math 4 in the standard, including trigonometric function, vector and trigonometric identity transformation. The third volume is equivalent to Math 2, a compulsory module in the standard, including the preliminary study of solid geometry and plane analytic geometry. The fourth book is equivalent to Math 5, a compulsory module in the standard, including solving triangles, sequences and inequalities. The fifth volume is equivalent to the compulsory module Math 3 in the standard, including preliminary algorithm, statistics and probability. The content order of these five volumes is slightly different from the standard, because one of the biggest characteristics of this textbook is to take vectors as the main line, connect algebra, geometry and triangle, use vectors to derive triangle formulas, analyze geometry, introduce complex numbers and solve various problems. It is necessary to learn vectors as soon as possible. The advantage of this processing is that the learning of (1) function is linked together. (2) Learning trigonometry early is beneficial to the application of trigonometric function knowledge in later courses and to the application of trigonometric knowledge in physics. (3) Arranging the algorithm, statistics and probability in the fifth volume is conducive to enriching the examples of the algorithm. Moreover, the basic mathematical knowledge is better mastered, and statistics and probability are easier to learn. The order and content of elective courses 1 and 2 are basically the same as those described in the standard. The writing style of elective courses 3 and 4 is as close as possible to popular science works, which is convenient for reading and self-study, and can also be used as a teacher for self-study. Senior high school mathematics study pays more attention to the role of mathematical concepts. At the beginning of each chapter, that is, before introducing important concepts, we arrange "question inquiry" or "mathematical experiment" columns, so that students can experience the emergence and development of mathematical concepts through practical activities or discussions. After the concept of mathematics is put forward, it will inevitably provide ideas and methods for dealing with related problems. In the column of "thinking method", the core ideas about mathematical methods will be summarized and analyzed, which is convenient for flexible application and extrapolation.
