前言课堂教学是小学数学知识学习的主阵地,也是学生获得系统性教学内容的重要方式之一,因此,提高小学数学课堂教学效率、优化教学方式至关重要。课堂教学是指教师在有限的时间内结合教学大纲的基本内容将数学知识传授给学生的过程,但老师作为教学主体虽然自身知识及经验较为丰富,但学生对于知识的理解、掌握却不尽相同,这就涉及到教学效率的问题。教学效率的提高涉及到教学模式、课堂氛围,又与教师的教学经验、练习题的布置有着密不可分的关系。因此,在有限的教学 Preface classroom teaching is the main front of primary school mathematics knowledge learning and one of the important ways for students to obtain systematic teaching content. Therefore, it is of vital importance to improve the efficiency of primary school mathematics classroom teaching and optimize teaching methods. Classroom teaching refers to the process of teaching mathematics knowledge to students by combining the basic contents of the syllabus with the teachers for a limited period of time. However, although teachers have abundant knowledge and experience as subjects, their understanding and mastery of knowledge are not the same , Which involves the issue of teaching efficiency. The improvement of teaching efficiency involves teaching mode, classroom atmosphere, but also has a close relationship with teachers’ teaching experience and the arrangement of exercises. So in limited teaching
