繁分数是小学教材中主要内容之一，并为中学阶段学习分式打基础，教学中应作为重点。由于计算的繁杂，错题现象较多，因此，也是我们教学中的难点。过去我在进行这部分内容教学时，总觉得教师教的吃力，学生学的费劲。近年来，改变了以往以繁分讲繁分的方法，充分利用学生已学过的知识去启发、诱导学生，逐步引出新知识，化难为易，变繁杂为简单，教学效果较好。 Fanfan is one of the main content of primary school textbooks, and lay the foundation for the learning stage of secondary school, teaching should be the focus. Due to the complexity of the calculation, the wrong phenomenon is more, therefore, is also difficult in our teaching. In the past when I was teaching this part of the content, I always felt that teachers taught hardworking and students learned hard. In recent years, it has changed the traditional methods of making elaboration on the traditional method of making elaboration, making full use of the knowledge that the students have learned to inspire and induce students and gradually lead to new knowledge.
