Mathematics core literacy refers to the basic qualities and abilities cultivated by students in the process of learning mathematics, including mathematical knowledge, mathematical thinking, mathematical methods, mathematical application, mathematical culture and mathematical emotion. These six elements are interrelated, complementary and isomorphic, and become a complete mathematical core literacy system.

1. Mathematical knowledge:

Mathematical knowledge is the basis of mathematical learning, including basic concepts and properties such as number recognition, operation, symbols, graphs, functions, probability statistics and so on. Students need to master these knowledge, form a good mathematical knowledge structure, and lay a foundation for subsequent study and application.

2. Mathematical thinking:

Mathematical thinking is the core of mathematical learning, including logical reasoning, abstract thinking, spatial imagination, mathematical modeling and so on. Students need to train strict logical reasoning ability, abstract thinking ability and spatial imagination ability through the training of mathematical thinking, which is of great significance to solving complex problems.

3. Mathematical methods:

Mathematical methods refer to the strategies and skills used in solving problems, including induction, deduction, analogy, conjecture, proof and so on. Students need to master these methods, form a problem-solving strategy system, and improve the efficiency and quality of problem solving.

4. Mathematical application:

Mathematical application refers to the application of mathematical knowledge and methods to practical problems, including solving mathematical problems in life, natural science and social science. Students need to have the ability to apply mathematics, apply mathematical knowledge and methods to the process of solving practical problems, and improve their ability to solve problems.

5. Mathematical culture:

Mathematical culture refers to the historical origin, development process and philosophical thought behind mathematical knowledge, mathematical methods and mathematical thoughts. Students need to understand the mathematical culture, the generation and development process of mathematical knowledge, the philosophical significance behind mathematical thought, and cultivate their interest and love for mathematics.

6. Mathematical emotion:

Mathematics emotion refers to students' attitude, interest, confidence and values towards mathematics learning. Students need to cultivate positive mathematics emotion, form lasting interest and self-confidence in mathematics learning, realize the value of mathematics to individuals and society, and thus stimulate the motivation of learning mathematics.

In a word, the six elements of mathematical core literacy are interrelated and complementary, and they are isomorphic into a complete mathematical core literacy system. In the process of mathematics teaching, teachers need to pay attention to the cultivation of these six elements, guide students to fully develop mathematical knowledge, mathematical thinking, mathematical methods, mathematical application, mathematical culture and mathematical emotion, and improve students' mathematical literacy and ability.
