分数是学生在已理解了平均分的意义,掌握了一些整数知识的基础上进行的学习,是从整数到分数,对数的概念的第一次扩展,也是一次质的飞跃,是非常重要的一项数学基础知识。在数学基础理论中,无论在意义、读法以及各部分的名称认识上,分数和整数都有很大的差异。对于三年级学生来说,他们的思维主要以感性认识为主,对直观具体的事物容易理解,学生学习认识分数时可能出现一些困难,但对于“一半”这样的词语在生活中并不陌生,让学生领悟出
Scores are the first significant extension of the notion of integers, scores, and logarithms, as well as a qualitative leap by students who have understood the meaning of average points and mastered some knowledge of integers, and are very important A basic knowledge of mathematics. In the basic theory of mathematics, the scores and integers are greatly different in meaning, reading method and the name recognition of each part. For third-graders, their thinking is mainly based on perceptual knowledge, easy to understand intuitive and specific things, students may encounter difficulties in learning to recognize scores, but for “” such a phrase in life is not Strange, let students comprehend
