What does the core literacy of mathematics mean?

Mathematics core literacy refers to the following points:

1, mathematical operation.

Mathematical operation refers to the process of solving mathematical problems according to the operation rules on the basis of clear operation objects. It mainly includes understanding the operation object, mastering the operation law, exploring the operation direction, selecting the operation method, designing the operation procedure and obtaining the operation result. Mathematical operation is the basic form of mathematical activities, a form of deductive reasoning and an important means to obtain mathematical results.

2. Logical reasoning.

Logical reasoning refers to the thinking process of deducing a proposition from some facts and propositions according to logical rules. There are mainly two kinds: one is from special to general reasoning, and the main forms of reasoning are induction and analogy; One is from general to special reasoning, and the main form of reasoning is deduction.

3. Intuitive imagination.

Intuitive imagination refers to the process of perceiving the shape and change of things with the help of geometric intuition and spatial imagination, and understanding and solving mathematical problems with graphics. Including understanding the positional relationship, morphological changes and motion laws of things with the help of space.

4. Mathematical modeling.

Mathematical modeling is a process of abstracting realistic problems mathematically, expressing problems in mathematical language, and establishing models to solve problems with mathematical knowledge and methods. It mainly includes: finding problems, putting forward problems, analyzing problems, establishing models, solving conclusions, verifying results and improving models in actual situations, and finally solving practical problems.

5. Data analysis.

Data analysis refers to the process of obtaining relevant data from the research object, analyzing and inferring useful information in the data by statistical methods, and forming knowledge. It mainly includes: collecting data, sorting out data, extracting information, establishing models, analyzing and inferring information, and drawing conclusions.

6. Mathematical abstraction.

Mathematical abstraction refers to the thinking process of obtaining mathematical research objects by giving up all physical attributes of things. It mainly abstracts the relationship between mathematical concepts and concepts from the relationship between quantity and figure, and abstracts the general laws and structures from the specific background of things, and expresses them with mathematical symbols or mathematical terms.
