In the primary school stage, the core literacy is mainly manifested as: sense of number, sense of quantity, sense of symbol, calculation ability, geometric intuition, sense of space, sense of reasoning, sense of data, sense of model, sense of application and sense of innovation.

The unique consciousness of number, quantity, symbol, reasoning, data and model in primary schools;

1, number sense mainly refers to the intuitive perception of logarithm and quantity, and the relationship between quantity and operation result. Can understand the meaning of numbers in real situations, and can use numbers to represent the number of objects or the order of things; Be able to make reasonable estimates and reasonable judgments under simple and real conditions; Can understand and express the simple quantitative law contained in things.

2. The sense of quantity mainly refers to the intuitive perception of the measurable attributes and size relationship of things. Knowing the meaning of measurement, we can understand the necessity of unified measurement units; Choosing the right measurement unit according to the actual situation will convert different units under the same measurement method; Can initially perceive the errors caused by measuring tools and methods, and reasonably obtain or estimate the measurement results.

3. Symbol consciousness mainly refers to the ability to perceive the mathematical function of symbols. Know the practical meaning of symbolic expression; Able to express quantities, relationships and general laws with symbols; Knowing that the operation rules and reasoning conclusions expressed by symbols are general, and preliminarily understanding the use of symbols is an important form of mathematical expression and mathematical thinking. ?

4. Reasoning consciousness mainly refers to the initial understanding of logical reasoning process and its significance. Reasoning consciousness is helpful to develop reasonable and orderly thinking habits and enhance communication ability, which is the empirical basis for forming reasoning ability.

5. Data awareness mainly refers to the perception of the meaning and randomness of data. Knowing that there are many problems in real life, first do research, collect data, understand the information contained in the data, form data consciousness, help to understand the random phenomena in life, and gradually develop the habit of speaking with data.

6. Model consciousness mainly refers to the preliminary understanding of the universality of mathematical models. Model consciousness is helpful to carry out interdisciplinary study and enhance the application consciousness of mathematics, which is the empirical basis for forming model concepts.
