The main contents of Graphics and Geometry are: the understanding of basic graphics in space and plane, the nature, classification and measurement of graphics;
Translation, rotation, axial symmetry, similarity and projection of graphics; Proof of the basic properties of plane graphics; Coordinate is used to describe the position and movement of a graph.
The main contents of Statistics and Probability are: collecting, sorting out and describing data, including simple sampling, sorting out survey data and drawing statistical charts; Processing data, including calculating average, median, mode, range, variance, etc. Extract information from the data and make simple inference; Simple random events and their occurrence probability.
"Comprehensive practice" is a learning activity with problems as the carrier and students' independent participation as the main body. In learning activities, students will comprehensively use the knowledge and methods of "number and algebra", "graphics and geometry" and "statistics and probability" to solve problems. At least one teaching activity of "integration and practice" is guaranteed every semester, which can be completed in class or combined inside and outside class.
In mathematics course, we should pay attention to developing students' sense of number, symbol consciousness, spatial concept, geometric intuition, data analysis concept, calculation ability, reasoning ability and model thinking. In order to meet the needs of the development of the times for talent training, mathematics courses should pay special attention to cultivating students' awareness of application and innovation.
