分数应用题是整个小学数学教学的重点和难点,在教学中,进行适当的单项训练,既可以帮助学生掌握分数应用题之间的数量关系,理清解题思路,把握解题规律,又可以发展学生的思维,培养学生迅速、灵活地解答分数应用题的能力。 The application of fractional questions is the key and difficult point in the entire primary school mathematics teaching. In teaching, proper individual training can help students grasp the quantitative relationship between the scores of applied questions, clarify the problem-solving ideas, grasp the law of solving problems, Develop student thinking and develop students' ability to quickly and flexibly answer fractional application questions.
