Symbol consciousness is the second core concept put forward in the Mathematics Curriculum Standard for Compulsory Education (20 1 1 Edition). The symbol consciousness mentioned here mainly includes two aspects, one is about the symbol of concept, the other is about the conformity of relationship; The 20 1 1 version of the curriculum standard changes the original "symbol sense" into "symbol consciousness", which is more in line with the value orientation of the curriculum objectives and the essential meaning requirements of mathematical symbols.

The connotation of symbolic consciousness is algebraic thought. Symbol is a special representation of mathematical abstraction, not only in algebra but also in geometry. Therefore, the mathematical thought contained in the symbol consciousness belongs to the abstract thought of mathematics rather than algebraic thought.

Advantages and functions of symbol expression: The teaching of using letters to express numbers has become the main way to cultivate students' sense of symbol. Use letters to represent the algorithm, the length, width, height, area formula of the figure and so on. The advantages of using letters to represent numbers are not only "simple", but also from special to general.

Closely combine the teaching of concepts, propositions and formulas in different periods to cultivate students' symbol consciousness. Because concepts, propositions and formulas are important components of mathematics curriculum, the focus of mathematics teaching, and are closely related to the expression and use of mathematical symbols. Therefore, "Curriculum Standard" puts forward specific requirements on the objectives and content standards of each period.
