在数学解题过程中,不同题目的解题思路不尽相同,都有各自的特殊之处。把握住这些特征,再具体问题具体分析,采用相应的解题办法,会大大减少同学们的解题时间,让解题过程变得轻松,还能提高解题的正确率。本文主要从以下面三个方面来引导同学们观察题目的特征,探究解题的方法:数形结合,直观推理;递推归纳,寻找规律;选择估值,比较分析。一、数形结合,直观推理对于有些数学题目,如果仅仅依靠死板的计算很
In the process of solving mathematical problems, different topics have different ideas and solutions, and all have their own special features. Grasping these characteristics, and then specific analysis of specific issues, the use of appropriate solutions to problems, will greatly reduce the students’ problem-solving time, making the process of solving problems easier, but also improve the accuracy of problem-solving. This article mainly from the following three aspects to guide students to observe the characteristics of the topic to explore the problem-solving methods: combination of numbers, intuitive reasoning; recursive induction, looking for the law; choice of valuation, comparative analysis. First, the combination of figures, intuitive reasoning For some mathematical problems, if only rely on the rigid calculation is
