分数应用题是整数应用题的发展,它既含有整数应用题的数量关系和解题思路,又有其独特的数量关系和解题思路,如果新课后不利用复习课进行比较、归类,只是就题论题,多做练习,学生便不能掌握分数应用题的特征和解题规律。因此,复习应有整体观,重点理清具体数量和当量分数间的对
The application of fractional questions is the development of integer application problems, which not only contains the quantitative relationship between integer application questions and problem-solving ideas, but also has its unique relationship between quantity and problem-solving ideas. If the new lesson does not use the reviewing class to compare and classify, Just to discuss the topic, do more exercises, students will not be able to grasp the characteristics of fractional applications and problem solving. Therefore, the review should have a holistic view, focusing on clarifying the exact number and equivalence between the scores
