方程(组)模型是数学的重要研究对象,刻画不等关系的数学模型——不等式(组),同样也是数学的重要研究对象.不等式(组)作为初中“数与代数”领域的重要内容之一,具有承上启下的作用.学好不等式(组),可以为函数等知识的学习打下坚实基础.一、体会普遍存在的不等关系,感悟“不等”与“相等”的辩证统一量与量之间的关系,是由相等关系和不等关系构成的.人的年龄大小、高矮胖瘦,物的形状结构等都表现出彼此之间的不等关
Equation (group) model is an important research object in mathematics, and the inequality (group), which is a mathematical model describing unequal relations, is also an important object of mathematics.Inequality (group) is important in the field of “junior high school” and “algebra” One of the content, has the function of enlightenment.Learning inequalities (group), can lay a solid foundation for the study of the function of knowledge, etc .. First, to understand the ubiquitous unequal relationship, perception “unequal ” and “equal ” The relationship between quantity and quantity of dialectical unity consists of equal relationship and unequal relationship.People’s age, height, weight and thinness, the shape and structure of objects, etc. all show different relations with each other
