《义务教育数学课程标准》十分强调数学与现实生活的联系,而数学知识本来就源于生活实践,经过总结形成理论,最终服务于生活。在小学数学教学中,不仅要考虑数学自身的特点,还应遵循学生学习数学的心理规律,强调从学生的生活经验出发,将教学活动置于真实的生活背景之中,为他们提供观察、操作、实践探索的机会。让学生亲身经历将实际问题抽象成数学模型并进行解释与应用的过程,进而使学生在理解数学知识的同时,在思维能 Mathematical Curriculum Standard of Compulsory Education places great emphasis on the connection between mathematics and the real life. Mathematical knowledge has its origin in the practice of life. After summarizing and forming the theory, it finally serves the life. In elementary mathematics teaching, we not only need to consider the characteristics of mathematics itself, but also follow the psychology of students to learn mathematics. Emphasis should be placed on students’ life experience, teaching activities should be placed in the real life background, to provide them with observation and operation , Practice exploration opportunities. Let students experience the abstract problem of the actual mathematical model and explain and apply the process, so that students understand the mathematical knowledge at the same time, in thinking
