列方程解应用题是小学教学的重点,也是小学教学的一个难点.列方程解应用题是在算术法的基础上进行教学的,但比用算术法解应用题要容易一些,因为它不受已知数量的限制,思维曲折性相对小一些;它以四则运算的基本应用和常见的数量关系为依据,综合应用了用字母表示数、解方程等知识,有特殊的解题思路和方法,有完整的解题步骤和程序.一、我们首先从找等量关系导入1.找等量关系.(1)A比B多30(2)A和B的和是100.
Column equation solution application problem is the focus of primary school teaching, but also a primary teaching difficulties.Equation of column equation solution is based on the arithmetic method to teach, but the arithmetic problem than using arithmetic to solve the problem easier because it is not It is based on the basic applications of the four operations and the common quantitative relationship. It uses a combination of knowledge of alphanumeric expressions and equation solving, and has special solutions to problems and methods. A complete solution to the problem steps and procedures.First, we first find the same amount of relations into 1. Find equal relationship (1) A more than B 30 (2) The sum of A and B is 100.
