数学教学离不开解题,教师通过解题将问题的分析过程、解题方法、数学思想教授给学生;学生通过解题,提升自己对数学知识的理解、掌握和应用的能力。显然,解题是检验教师的教和学生的学的重要手段,在解题过程中对题目的信息进行解读、处理,寻找正确的解题思路是解题的关键,本文通过对一道习题的评析,探讨解题的策略。一、问题呈现 Mathematics teaching can not be separated from problem solving. Teachers solve the problem by analyzing the problem solving process, problem solving methods and mathematical thinking to students. Students solve their problems and improve their ability to understand, grasp and apply mathematical knowledge. Obviously, problem solving is an important means to test teachers ’teaching and students’ learning. It is the key to solve the problem that the problem information is interpreted and dealt with in the process of problem solving. This article analyzes the problem , To explore the solution to the problem. First, the problem is presented
