论文部分内容阅读
本学期我担任五年级数学教学(苏教版五年级上册),这册书计算教学占很大一部分(小数加减法和小数乘除法),大家都知道知识不难,但正确率不高。我在教这部分内容时做到:每节课课前3分钟口算练习。通过几次检测,老师们都感到这班学生的计算能力要高于其它班学生,在期中分析会上我谈了这个“秘密”。下面我来谈谈口算教学的一些想法。一、口算教学是计算的基础口算是指不借助任何计算工具,直接通过思维活动
This semester, I served as fifth grade mathematics teaching (Jiangsu Education Fifth Grade), this book accounting teaching accounted for a large part (decimal addition and subtraction and decimal multiplication and division), we all know that knowledge is not difficult, but the accuracy is not high. When I was teaching this part, I did it: 3 minutes before each lesson. Through several tests, teachers felt that the students in this class had higher computational power than other classes, and I talked about this “secret” during the mid-term analysis. Let me talk about some of the ideas of oral arithmetic. First, the calculation of teaching is the basis of calculation Mouth means that without any calculation tools, directly through the thinking activities
