《数学课程标准》指导我们在小学数学课堂教学中要注意学生智力和数学思维能力的开发,结合教学内容改进教学方式方法,从而培养学生的多种能力。其中小学阶段接触的一些平面知识是学生空间思维和想象能力提高的基础,关系到学生数学学习潜力和其终身发展。因此,如何让学生对平面知识感兴趣、掌握并灵活运用显得非常重要。
The standard of mathematics curriculum guides us to pay attention to the development of students ’mental ability and mathematical thinking ability in primary mathematics classroom teaching and improve the teaching methods and methods in order to cultivate the students’ various abilities. Some elementary knowledge of elementary school contact is the basis of students ’spatial thinking and imagination. It relates to the potential of students’ mathematics learning and their lifelong development. Therefore, how to make students interested in the plane of knowledge, grasp and flexible use of it is very important.
