In this paper I have tried to find the points which current Math teachers should reconsider in their classes and suggested how to improve the teaching methods in the class. For these answers, I analysed Teaching plans of 30 Math teachers in K province and observed their model classes. The conclusions acquired by these observations are the followings. First, Math teachers should have a great deal of enthusiasm in their classes. Second, Math teachers must understand the curriculum. Third, Math teachers have to understand their students. Fourth, Math teachers should endeavor with other teachers through the workshop. Fifth, Math teachers should be professional and open-minded to make their classes public anytime.
