初中数学中列方程(组)解应用题是学生学习的一个难点,解答应用题首先将实际问题转化为数学模型,其次用代数式表示出各个己知量和未知量,最后.找出问题中的等量关系,然后建立方程(组).应用问题是学习的一个难点,要解决难点关键是找到分析思考问题的途径.怎样让学生从繁多的数量中理出头绪,找到等量关系列出方程呢?下面是我对课本一道探究题的教学片断,重在使学生抓住方法(列表格、标 Junior high school mathematics column equation (group) solution is a difficult problem for students to learn, answer practical problems first of all practical problems into mathematical models, followed by algebraic expression of each known amount and unknowns, and finally find out the problem Equations, and then establish the equation (group) .Application problem is a difficult learning, to solve the crux of the problem is to find ways to analyze the problem of thinking.How to let students from a large number of clues to find the amount of relations to find the equation Here’s my teaching piece on exploring the textbook, focusing on getting students to grasp the methods (list boxes,
