我们生活在一个变化的世界中,从数学的角度去研究变化的量,讨论它们之间的关系,这将有助于我们更好地去认识世界和预测未来,为此,同学们在学习“变量之间的关系”时务必注意以下几点:一、重点、难点、考点分析重点:通过经历探索和表示变量之间关系的过程,获得对表格、图像、关系式等多种表示方式的体验,能读懂表格、图像、关系式所表示的信息,并能运用表格和关系式刻画一些具体情境中变量之间的关系, We live in a changing world, studying the amount of change from a mathematical point of view, discussing the relationship between them, which will help us to better understand the world and predict the future, for which students are learning “The relationship between variables ” be sure to pay attention to the following points: First, the key, difficult points, test centers Analysis of the key points: through the process of exploration and representation of the relationship between variables, access to forms, images, relationships and other expressions Of the experience, can read the form, images, relationships expressed by the information, and can use tables and relationships to characterize the relationship between variables in a specific context,
