You may find unexpected paths and beautiful scenes at any time, and not everything must follow a fixed but unpleasant journey.” With the new curriculum The deepening of reform, the classroom has become a teacher-student exchange, students exchange activities, teacher-student interaction process of thinking in the classroom is a teacher-student collision, mutual acceptance, life and accommodation flow of each other. Therefore, teachers should be able to keenly capture the accidental points in the classroom, seize the opportunity to teach, to promote the dynamic generation of mathematics classroom, so that the classroom full of vitality. First, guide discrimination, inspire thinking, to generate
