数学知识来源于生活,又服务于生活。数学语言、数学符号是对生活中物体的数量、特征等的抽象表达,是对图形的变化规律、联系等的总结、概括……在教学中要让学生通过实践活动,体验和理解数与形的结合,让学生在动手做的过程中探索创新。一、查阅史料、体会价值学习新知识之前,让学生动手查阅资料,了解数学的背景知识和相关的历史资料。这样,学生对所学知识就有一个深层次、广角度的认识。
Mathematical knowledge comes from life, but also serve life. Mathematical language, mathematical symbols are the abstract expression of the number and characteristics of objects in life, which are the summary and generalization of the changing rules and connections of the figures. In teaching, students should be allowed to experience and understand the numbers and shapes through practice activities A combination of let students explore innovation in the hands-on process. First, access to historical data, experience value Before learning new knowledge, let students first hand access to information to understand the background knowledge of mathematics and related historical information. In this way, students have a deep, wide-angle understanding of what they have learned.
