Because math class has a strong theoretical, often bring to the students' learning boring, boring, to improve student learning and improve the efficiency of classroom teaching achievement, teachers should choose a good classroom teaching methods, classroom teaching is not a single fixed the teacher can use a variety of import methods, and these methods are also introduced into the same thing, but if you use for different students the same import method, the effect will be a big difference, therefore, be based on teacher knowledge students have learned, with close method to understand life, flexible design knowledge structure into the classroom. The present paper on high school mathematics in the classroom teaching methods and case studies to make a brief exposition.

因为数学课有较强的理论性，往往给学生的学习带来枯燥、乏味，为提高学生的学习效率和提高课堂的教学成果，教师应该选择一个好的课堂教学方法，课堂教学模式不是单一固定的，教师可以用多种导入方法，而这些导入方法也是殊途同归的，但是如果针对不同的学生用同一种导入方法，效果相差会很大，因此，教师需根据学生已学的知识点，用贴近生活易懂的方法，灵活的设计知识结构导入课堂。本论文就中学数学在课堂导入方法及案例分析做一个简要的阐述。

Because of the strong theoretical nature of mathematics course, it often brings students boring and boring learning. In order to improve students' learning efficiency and improve classroom teaching results, teachers should choose a good classroom teaching method. The classroom teaching mode is not single and fixed. Teachers can use a variety of introduction methods, and these introduction methods are also different, but if different for different According to the knowledge points that students have learned, teachers need to use the method close to life and easy to understand, and design knowledge structure flexibly to lead into the classroom. This paper makes a brief exposition on the methods and case analysis of middle school mathematics introduction in the classroom.
