找出应用题中数量间的相等关系,是列方程解应用题的中间环节,但学生初学时对此常感到困难。教学时,应通过实物、图解等直观的方法来帮助学生分析题中有哪些基本数量关系,这些数量关系间又有什么联系,在此基础上引导学生找出等量关系。那么,怎样引导学生找出等量关系呢?1．教育学生时理解并掌握一些常见的数量关系,从而得出等量关系。应用题中的数量关系有一
Finding the equal relationship between the number of applied questions is an intermediate part of the solution to the problem of column equations, but students often find it difficult to begin with. Teaching, should be through physical, graphical and other visual methods to help students analyze the question of what the basic quantitative relationship between the relationship between the number of what is the relationship between, on the basis of guiding students to find the same relationship. So, how to guide students to find the same amount of relations? When educating students, understanding and mastering some common quantitative relationships leads to equivalent relations. The number of questions in the application of a relationship
