The main purpose of this study is to analyse the intuitive thinking about the concept of infinity for the students in the high school, and to provide an effective teaching guidance to enlarge the correct concept of the infinity. We choose mathematical high-achieve 80 students who were above 33% in the math mid-term test. After 1st paper test and questionnaire, we analyze the answers about their intuitive thinking about infinity. 57.5% of the students have the correct concept of infinty. We made 10 activity papers which took 1 hours for each paper, and applied them
to the students. After 2nd paper test and questionnaire, we analyze again their answers about the infinite. Then 93.7% of the students gave the correct answers about infinty. We understand the importance of the careful advice and effective guidance for teaching the concept of infinity. And to enlarge the concept of the secondary intuition of infinity, teachers must prepare the real activity based model for infinity and have careful corcern to the students.
