动手操作是发展学生思维,培养学生数学能力最有效的途径之一。新编小学数学教材的特点之一,是重视直观教学,增加了学生的实践活动和动手操作内容、那么,如何进行操作活动呢?一、注意操作方法的恰当性操作方法多种多样,没有统一的模式、统一的要求。教师根据操作内容,应适当启发、精心设计合乎逻辑的操作方法。这样不仅能使学生获得知识更容易,而且有利于提高学生的逻辑思维能力。例如:对于平行四边形面积,我是这样教学的:先设计一套思考题:1.你知 Hands-on operation is one of the most effective ways to develop students 'thinking and students' mathematical abilities. One of the characteristics of the new primary school mathematics textbooks, is to emphasize the intuitive teaching, an increase of students practice activities and hands-on content, then, how to operate it? First, pay attention to the appropriateness of the method of operation A variety of operating methods, there is no uniform The model of uniform requirements. According to the operation of teachers, teachers should be inspired, carefully designed logic method of operation. This will not only make it easier for students to acquire knowledge, but also help to improve students' logical thinking ability. For example: For the parallelogram area, I teach this: first to design a set of questions: 1. You know
