“线段图”是由一定意义线段、箭头、数字等组合在一起构成的,用来表示应用题中的数量关系,帮助学生分析题意、解答问题的一种图形。它的特点是形象直观,能够引起学生的注意和兴趣,是从抽象的文字到直观的再创造、再演示的过程。教会学生利用线段图辅助解题,是小学数学教学一个不可忽视的任务。一、从学生学习需要来激发学生画线段图之欲所有的复杂问题都可细分为若干个小问题,每个细小的问题都可采用简单的线段图来表示其中的数量关系。所以,从简单问 “Line graph ” is composed of a certain sense of line segments, arrows, numbers, etc., used to represent the relationship between the number of questions in the application to help students analyze the problem, a graphic answer to the problem. It is characterized by visual image, can arouse the students’ attention and interest, from the abstract text to the intuitive re-creation, and then the demonstration process. Church students use line drawings to help solve problems, is a primary school mathematics teaching can not be ignored task. First, from the students need to learn to stimulate students to draw line Desire All the complex issues can be subdivided into a number of small problems, each small problem can be a simple line graph to represent the number of relationships. So, from simple questions
