画线段图的方法,是帮助学生由具体形象思维向抽象逻辑思维过渡的有效方法。学生学会了画线段图并形成能力,就能加深对数量关系的理解,进而提高解答应用题的能力。我在教学中,注意对学生画分析图解应用题能力的培养,下面谈两点做法。一、抓好分数应用题线段图的教学教学分数应用题时,线段图的教学是十分重要的。许多复杂的分数应用题,如果抽象地去思考,往往难以找到解题的线索,但画图,就很容易找到解题的思路。而事实上,许多稍复杂的分数应用题,学生是很难正确地画出线段图的,一旦教会学生合理地画出线段,解答也就不难了。例如: 某校五年级两个班共种树100棵,一班所种
The method of drawing a line segment diagram is an effective way to help students to transition from the concrete image thinking to the abstract logical thinking. When students learn to draw line drawings and form their abilities, they can deepen their understanding of the quantitative relationship and thus improve the ability to answer application questions. In my teaching, I pay attention to cultivating students’ ability to analyze graphic application questions. First, do a good job of the fractional application of the line segment of the teaching of teaching scores when applied, the teaching of line drawings is very important. Many complicated score questions, if abstractly thinking, often difficult to find clues to solving problems, but the drawing, it is easy to find a solution to the problem. In fact, many of the more complicated application questions require that students find it hard to draw the line art correctly. Once the students are taught to draw the line rationally, it is not difficult to answer the question. For example: a five-year grade two classes a total of 100 trees planted a class
