新编小学《数学》第一册是根据《全日制十年制学校小学数学教学大纲(试行草案)》(以下简称《大纲》)编写的。这是小学生学习数学的开始。编好这一册教材,搞好这一册教材的教学,使学生迈好第一步,对于打好数学基础,提高数学教学质量,具有十分重要的意义。这一册教材的主要内容是读写100以内的数,口祘一位数加法和相应的减法(即10以内的加、减法和20以内的进位加法、退位减法)。这些是学习多位数四则计祘的基础,务必使学生一开始就学好这些内容。为了使学生很好地掌握这些基础知识和计祘能力,结合一年级小学生的年龄特点,在内容上作了如下安排。
New elementary school “mathematics” first volume is based on “full-time ten-year school mathematics teaching syllabus (draft)” (hereinafter referred to as the “outline”) prepared. This is the beginning of elementary school mathematics learning. To compile this textbook, improve the teaching of this textbook, and make the students take the first step, it is of great significance for laying a good foundation for mathematics and improving the quality of mathematics teaching. The main content of this book is to read and write the number of 100 within the number of mouth 加 plus one-digit addition and the corresponding subtraction (that is, less than 10 plus, subtraction and carry within 20 plus addition, abort subtraction). These are the foundations for learning a multi-digit, four-figure plan, so that students should learn the content right from the beginning. In order to enable students to master these basic knowledge and ability, combined with the characteristics of first-year primary school age, made the following arrangements in the content.
