“求一个数是另一个数的几倍”的应用题是从一个数里面有几个另一个数的问题发展起来的。它与求一个数的几倍是多少的应用题只是已知条件与未知条件发生了变化。教学过程中必须沟通知识间的内在联系,组建认知结构,使学生在理解意义的基础上懂得用除法计算的道理,并能用这个知识解应用题。 The question of the application of “finding a number a few times more than another number” was developed from the question of having several numbers in another. It is a few times the number of applications with a few questions is only known and unknown conditions have changed. In the process of teaching, we must communicate the internal relations among knowledge, construct the cognitive structure, make students understand the reasoning of division based on the meaning, and use the knowledge to solve the problem.
