多边形的面积教学在小学数学中是一个非常重要的内容构成,这部分几何知识和其他知识间的联系体现的较为紧密,是在学生对于各种基本图形面积计算熟悉的基础上的一种延伸学习。对于大部分学生来说,这部分内容的学习存在一定的理解难度,学生不知道多边形到底应当如何界定,真正到面积计算时也容易产生各种错误。教师在展开这一主题的教学时,要从培养学生探究能力的角度出发,进行思维上的引导。让学生对于多边形有更 Polygon area teaching in primary school mathematics is a very important content composition, this part of the relationship between knowledge and other knowledge reflected more closely, is an extension of the learning of students for all kinds of basic graphics area based on an extended learning . For most students, this part of the content of learning there is some difficulty in understanding, students do not know how to define the polygon in the end, the real calculation of the area is also prone to errors. Teachers in carrying out the teaching of this topic, from the perspective of training students to explore the ability to carry out the thinking of the guide. Have students have more to do with polygons
