分数是小学数学的重要内容之一,它是小学阶段学生数学学习的重点,也是难点。通常,当学习分数开始,有相当一部分学生就觉得数学比较难学,特别是有关分数的问题解决,学生出现的困难更多,两极分化现象更严重。而分数意义是分数这一内容的重点,也是难点,因此,有效教学分数意义显得尤为重要。在日常的教学中,对分数意义的教学,教师往往比较重视分数语言意义的理解,而忽视其他角度的理解,且没有形成层次。笔者以为,分层理解分数的意义,正确把握各层分数意义的特点。对于帮助学生理
Scores are an important part of primary school mathematics, which is the focus of primary school mathematics students, but also difficult. Usually, when the learning score starts, a considerable number of students think that math is more difficult to learn. Especially when it comes to solving problems with scores, students have more difficulties and more extreme polarization. The significance of the score is the focus of this part of the content, but also difficult, therefore, the significance of effective teaching scores is particularly important. In daily teaching, for the teaching of fractional meaning, teachers tend to pay more attention to the understanding of the meaning of fractional language while neglecting the understanding from other angles and do not form a hierarchy. I believe that the meaning of stratified understanding of scores, the correct grasp of the characteristics of the meaning of the various layers. To help students manage
