论文部分内容阅读
多位数的读法和写法,是小学数学基础知识之一。学好这部分内容,对进一步学习有很大影响。今年下半年使用的五年制小学数学第五册,对这一单元教材在编排上、教学要求上都作了修改,把亿以内的数的读、写作为重点,使教师便于教,学生便于学。为此,教学这一单元,必须掌握教材,改进教法。下面谈谈我们这方面的学习体会。一、领会新教材的编写意图,掌握教材内容和要求。1.螺旋式上升。从教材上看,多位数的读法和写法,是整数的认识四个阶段中的最后一个阶段。主要包括两个方面的内容。一是让学生了解日常生活和生产中,需要用到比万大的数。然后认识新的
Multi-digit reading and writing, is one of the basic knowledge of elementary mathematics. Learn this part of the content, have a great impact on further learning. The fifth year of the five-year primary school mathematics used in the second half of this year has been revised in terms of the layout of the unit teaching materials and teaching requirements. The emphasis is on reading and writing the number of teachers within a hundred million, facilitating teachers' learn. To this end, teaching this unit, we must master the teaching materials, improve teaching. Here to talk about our learning experience in this area. First, understand the compilation of new textbooks intended to master the textbook content and requirements. Spiral rise From the teaching material point of view, multi-digit reading and writing is the last of the four phases of integer recognition. Mainly includes two aspects. First, let students understand daily life and production, need to use more than a few million. Then meet new ones
