In Hubei Wuhan to participate in the 11th deepening elementary mathematics teaching reform exchange meeting, listening to Jiangsu Province, Dong winter teacher taught “rectangular and cube understanding ” a lesson, for Wu superb teaching art “Simple atmosphere” teaching design impressed. Teacher Wu This lesson is level, true, solid, concise, clear and smooth, and has a wonderful classroom. First, the operation experience Perception operation is a means of mathematical learning, the purpose is to better promote students understanding of mathematical knowledge, can use mathematical language, symbols to express and exchange; experience is the learner’s psychological behavior, the operation only Can provide learners with the conditions of experience, experience can not only have a deeper understanding of mathematical content, but also have a positive emotion. The acquisition of students’ mathematics experience is mainly through the practice of operation, and the activity of operation is the learning and living of many kinds of sensory coordination and participation
