数学是很多专业学科的基础,因此小学数学就是学好数学的第一步,小学数学教学重点在于要教会学生建立解决实际问题的思维和方法。在小学数学中,解决问题的策略有画图、列表整理、找规律、转化、列举等,其中用画图的方法可以帮助学生正确地理解题意,培养学生宽广的思维能力和学习数学的兴趣。一、意识培育,引发学生画示意图的需要曾经做过这样一个实验(四年级下册教材):首先,拿一个实际问题为例进行分析,如图1所示,显然题目就是求原来草
Mathematics is the basis of many specialized disciplines. Therefore, primary school mathematics is the first step to learning mathematics. Primary mathematics teaching focuses on teaching students to establish thinking and methods to solve practical problems. In primary school mathematics, the strategies for solving problems include drawing, listing, finding laws, transformations and enumerations. Drawing methods can help students to correctly understand the questions, develop students' broad thinking ability and interest in learning mathematics. First, to cultivate awareness, the students need to draw the intention of drawing such an experiment (Grade IV textbook): First of all, to take an actual problem as an example for analysis, as shown in Figure 1, obviously the subject is to seek the original grass
