分数(百分数)应用题是小学数学教学的重点和难点,它主要包括“求一个数是另一个数的几分之几”、“求一个数的几分之几是多少”和“已知一个数的几分之几是多少,求这个数”三类应用题。在分数应用题的教学中,必须重视概念教学,改进教学方法,培养学生的思维能力。以扩展、深化学生的数学知识,提高学生分析问题和解决问题的能力。一、重视概念教学,打好应用题教学的基础学生在初学分数应用题时,所发生的不少错误都出
Points (%) Application questions are primary and secondary mathematics teaching emphasis and difficulty, it mainly includes “find a number is a few of another number,” “find a few a few is the number of” and “known a What is the fraction of the number is how many, find the number of ”three types of application questions. In the teaching of fractional application questions, we must attach importance to the concept of teaching, improve teaching methods, develop students' thinking ability. To expand, deepen students 'mathematical knowledge, improve students' ability to analyze and solve problems. First, pay attention to the concept of teaching, lay the foundation for the application of teaching problems Students in the beginner score application questions, a lot of mistakes have been made
