The Mathematics Curriculum Standard states that mathematics teaching activities must be based on the students’ level of cognitive development and existing knowledge and experience, and allow students to experience the practical problems abstracted into mathematical models and interpret them And the application of the process ”“ Through observation, experiment, guess, proof and other mathematical activities, the development of emotional reasoning ability and the initial deductive reasoning ability, an orderly and clearly explain their point of view ”" effective mathematical learning The process can not simply rely on imitation and memory, teachers should guide students to take the initiative to observe, experiment, guess, verify, push
