一、引言《比例》这个知识点小学数学六年级才正式引入,但是,其实学生在过往的课程学习中对于这个知识点或多或少已有涉及。比例和学生从前学过的除法、分数等都有所关联,教师在教学这个新课内容时可以借助学生已有的知识积累为辅助,让学生能够更快的吸收这部分新课内容。同时,值得注意的是,学生很容易将这几个知识点弄混淆,这也是学生对 I. INTRODUCTION The “proportionality” of knowledge is only introduced into the sixth grade of primary school mathematics. However, in fact, students have more or less involved this knowledge in previous course learning. The proportions are related to the divisions and scores previously learned by the students. When teaching this new course, teachers can assist students with the accumulation of existing knowledge so that students can absorb this part of the new course more quickly. At the same time, it is noteworthy that students can easily confuse these points of knowledge, which is also the students
