众所周知,计算教学是支撑小学数学教学的最基本框架,占据小学数学一半以上的教学时间。在现行的教材中,简便计算是计算教学的一个组成部分,到了三四年级学习了运算定律之后则明确地提出了“简便计算”这样的教学要求,什么是简便计算呢?它在小学数学教学的地位到底如何呢?我们有必要做进一步的认识和探讨。一、对简便计算的再认识简便计算,从字面上理解,应该是使计算变得简单或者说是简单地计算。百度百科指出:简便计算是一种特殊
As we all know, computing teaching is the most basic framework to support primary school mathematics teaching, accounting for more than half of primary school mathematics teaching time. In the current teaching materials, simple calculation is an integral part of the calculation of teaching, to the third and fourth grade after learning the law of arithmetic is clearly put forward “easy calculation ” teaching requirements, what is easy to calculate it? What is the status of mathematics teaching? We need to do further understanding and discussion. First, to re-understand the simple calculation Simple calculation, literally, should make the calculation easier or simply calculated. Baidu Baike pointed out: simple calculation is a special
