数学单元复习课就是要把平时相对独立进行教学的知识,以再现、整理、归纳等方法串起来,进而加深学生对知识的理解和贯通,其基本任务就是整理知识,使之系统化、清晰化,并具有拓展性。长期以来,复习课难上,复习课教学几乎成了小学数学改革的一大难题。有人说:“平时数学教学是栽活一棵树,那么复习过程就是育好一片林”。这句话也充分说明了复习的重要性。 Mathematics unit review class is to usually relatively independent of teaching knowledge, to reproduce, organize, inductive and other methods of string together, and then deepen the students understanding of knowledge and through, its basic task is to organize knowledge, make it systematic and clear , And is scalable. For a long time, the review class is hard to come by, and the reviewing class has almost become a major problem in the elementary mathematics reform. Some people say: “The usual mathematics teaching is planting a tree, then the review process is to cultivate a forest.” This sentence also fully illustrates the importance of review.
