This article advocates the interactive teaching in the mathematics classroom of elementary school through four basic links such as setting up the environment of personal exploration, group discussions under the guidance of teachers, inducing and summarizing after intergroup communication, arranging task-based activities and expanding the extensibility of the classroom.
