在小学六年级数学教学中,用分数乘除法解决问题是教材中的重点也是难点。教学过程中,学生往往依赖于离散的解题经验,对于单位“1”、分率这些抽象的概念学生不易理解,缺乏对有关数量关系的辨析。如何突破这个教学难点?带着这个问题,对这块教学知识进行了以下教学尝试。 Sixth grade in primary school mathematics teaching, using fractional division method to solve the problem is the focus of the textbook is also difficult. In the process of teaching, students often rely on discrete problem-solving experience. For the unit of “1”, students of fractional abstraction are not easy to understand and lack of discrimination in relation to the quantity. How to break through this difficult teaching? With this question, the teaching of this teaching the following teaching attempt.
