小学数学中有很多概念:数的概念、运算的概念、常见的量的概念、几何形体的概念、比和比例的概念、方程的概念以及统计与概率的概念等。数学概念的引人,是数学概念教学的第一个环节,也是十分重要的环节。由于各类数学概念的发生与形成过程不尽相同,因此需要根据概念的产生背景和学生的具体情况,找准概念教学的切人点。这样可以激发学生的学习兴趣和积极性,为学生感知、理解和应用概念奠定坚实的基础。一、创设动手操作的游戏活动在概念数学中,教材通常都呈现了一定的生活情境,引
There are many concepts in elementary mathematics: the concept of numbers, the concept of operations, the concept of common quantities, the concept of geometric shapes, ratios and proportions, the concept of equations and the concepts of statistics and probability. Introducing the concept of mathematics is the first part of the teaching of mathematical concepts, but also a very important part. Due to the different occurrences and formation processes of various mathematical concepts, it is necessary to identify the cut point of conceptual teaching according to the background of the concept and the specific circumstances of the students. This stimulates students’ interest and enthusiasm in learning and lays a solid foundation for students to perceive, understand and apply concepts. First, the creation of hands-on game activities In conceptual mathematics, textbooks are usually presented a certain life situation, cited
