初中数学课程标准(国外英文资料) In the third stage (7 ~ 9 grade) Number and algebra In this period, students will learn real, formal and fractional, equations and equations, inequalities and inequalities, functions such as knowledge, explore the relationship and rule of implication number, shape and practical problems, preliminary master some effective representation, processing and exchange relationship between the number and the variation of the tool, the development of symbol sense close contact, experience mathematics and real life, enhance the consciousness of application, improve the ability to use algebraic knowledge and methods to solve the problems. In the teaching, should pay attention to let students understand the relationship between quantity and change of the basic laws in practical background, pay attention to enable students to experience the establishment of mathematical model, estimation, solution, solution is verified the correctness and rationality of the process from the practical problems, we should strengthen equation, inequality, functions such as connection, introduces relevant algebraic geometry background the content should avoid tedious operation. (a) specific objectives 1. number and formula (1) rational number The understanding of the significance of rational number, can use the axis point representation of rational numbers, is the size of a rational number. With the help of the axis of understanding opposite number and absolute value of the significance, opposite number will seek a rational number and absolute value (absolute value without letter symbols in). The understanding of the significance of involution, grasp the rational number of add, subtract, multiply, divide, involution and simple mixed computing (three step based). Understand the operation law of rational numbers, and simplify the operation by using the operation law. Can use the operation of rational numbers to solve simple problems. We can make a reasonable explanation and inference o
