Through the mathematics study in the compulsory education stage, students can: 1, acquire the basic mathematics knowledge, skills, ideas and experience necessary for adapting to social life and further development. 2. Understand the relationship between mathematics knowledge, mathematics and other disciplines, mathematics and life, and use mathematical thinking mode to think, thus enhancing the ability to find, ask, analyze and solve problems. 3, understand the value of mathematics, improve interest in learning mathematics, enhance confidence in learning mathematics well, develop good study habits, and have a preliminary sense of innovation and a scientific attitude of seeking truth from facts. The "overall goal" is as follows: knowledge and skills * experience the abstract operation and modeling of numbers and algebras, and master the basic knowledge and skills of numbers and algebras. * Master the basic knowledge and skills of graphics and geometry through the process of abstraction, classification, nature discussion, movement and position determination of graphics. * Experience the process of collecting and processing data in practical problems, analyzing problems with data and obtaining information, and master the basic knowledge and skills of statistics and probability. * Participate in comprehensive practical activities, solve simple practical problems by comprehensively applying mathematical knowledge, skills and methods, and accumulate experience in mathematical activities. Mathematical thinking * Experience algebra to express the functions of operation and geometric intuition, initially establish a sense of number, symbol and space, and develop image thinking and abstract thinking. * Understand data and stochastic phenomena, understand the significance of statistical methods, and develop data analysis and stochastic concepts. * In participating in observation, experiment, Cai Xiang, Zheng Ming, comprehensive practice and other mathematical activities, cultivate the ability of rational reasoning and deductive reasoning, and clearly express their ideas. * Learn to think independently and understand the basic ideas and ways of thinking of mathematics. Problem solving * Initially learn to find and ask questions from the perspective of mathematics, comprehensively use mathematical knowledge and other knowledge to solve simple mathematical problems, and cultivate application awareness and practical ability. * Get some basic methods to analyze and solve problems, experience the diversity of problem-solving methods, and cultivate innovative consciousness. * Learn to cooperate and communicate with others. * Initially form a sense of evaluation and reflection. Emotional attitude * Take an active part in mathematics activities, and have curiosity and thirst for knowledge about mathematics. * Experience the pleasure of success, exercise the will to overcome difficulties and build self-confidence in learning mathematics well. * Understand the characteristics and value of mathematics. * Develop the habit of questioning and form a realistic attitude. The four aspects of the overall goal are not independent and separated from each other, but an organic whole that is closely linked and blended with each other. In the course organization and teaching activities, four objectives should be considered at the same time. The realization of these goals marks students' good mathematics education and is of great significance to students' all-round, sustained and harmonious development. The development of mathematical thinking, problem solving and emotional attitude can not be separated from the learning of knowledge and skills, which must be conducive to the realization of the other three goals.
