新课程标准要求下,小学数学教学要与生活实际紧密相连,从已有的经验出发,开辟出一条新的教学道路。有人把教学比作一门艺术,如何使这门艺术变得更为有效,是需要教师去思考的。在小学数学,尤其是高年级小学数学教学中,创新教学模式,引入情境教学,是提高教学实用性、时效性的一种必要手段。 Requirements of the new curriculum standards, primary school mathematics teaching should be closely linked with the actual life, starting from the existing experience, open up a new teaching path. Some people regard teaching as an art. How to make this art more effective is that it requires teachers to think. In primary school mathematics, especially in the first grade primary school mathematics teaching, innovating the teaching mode and introducing situational teaching is a necessary means to improve the practicality and timeliness of teaching.
