方程是刻画现实世界的有效模型,列方程解应用题是初中数学教学的重点和难,对培养学生分析问题、解决问题的能力以及体会数学的价值具有重要的意义。如何通过对实际问题中的数量关系的分析,简单快捷地寻找到解决问题的策略呢?一、把握教材,明确方程应用题重点苏科版初中数学有关列方程解应用题内容:七(上)4.3用方程解决问题。主要是要求学生能根据具体问题中的关系列出方程,体会方程是刻画现实世界数量关系的有效模
Equation is an effective model to depict the real world. Application of column equation solution is the key and difficult of junior high school mathematics teaching. It is of great significance to train students’ ability of analyzing and solving problems and realizing the value of mathematics. How to find the solution to the problem through the analysis of the quantitative relationship among the practical problems? First, grasp the teaching material, a clear application of the equation problem focus Suke version of junior high school mathematics related column equation solution application questions: seven (on) 4.3 solve the problem with equations. Mainly require students to be based on the relationship between the specific problems listed in the equation, experience is to describe the relationship between the number of real-world relationship between the effective mode
