一、知识迁移师:我们知道数学是一门很有用的学科,它可以帮助我们解决很多生活中的实际问题。以前我们已经学会了利用方程的思想来解决问题,请你回想一下这种方法的基本思路是什么?生:一审、二设、三列、四解、五验、六答。师:以上步骤中,审题是基础,通过审题得出等量关系,然后根据等量关系列出方程求解。今天我们一起来研究一下,当生活中出现了这些问题的时候,方程能否帮助我们解决问题?除了方
First, the knowledge transfer division: We know that mathematics is a very useful discipline, it can help us solve many practical problems in life. Before we have learned to use the idea of equations to solve the problem, please think back to what is the basic idea of this method? Students: First, Second, Third, Fourth, Five, Six. Teacher: In the above steps, examining questions is the basis for obtaining equivalent relations through trial examinations, and then solving the equations according to the equivalent relations. Today we work together to study, when these problems occur in life, the equation can help us solve the problem?
