一、明确目标,突出重点小学数学拥有众多的知识点,虽然前后知识之间有联系,但编排体系呈现出既相对集中又绝对分散的特点,分布横成块纵成线,交叉出现。面对众多的点、线、面,必须在把握学生已有知识、经验基础上,明确目标,突出重点,抓准难点,优化复习内容。如“数和数的运算”一节中,数的意义和四则运算的意义是基干内容,是理解的重点,而一些 First, a clear goal, highlighting the point of primary school mathematics has a large number of knowledge points, although there is a link between before and after the knowledge, but the layout of the system has shown both relatively concentrated and absolutely decentralized features, distributed into blocks into lines, cross appear. In the face of numerous points, lines and surfaces, we must, on the basis of grasping the students’ existing knowledge and experience, set clear objectives, highlight the key points, grasp the difficulties and optimize the contents of the review. As in the “Number and Number of Operations” section, the meaning of numbers and the meaning of the four operations are the content of the basics, which is the point of understanding, while some
