一、整体修订情况(一)根据《义务教育数学课程标准(2011年版)》(以下简称《标准(2011年版)》)“四基”的要求,对教材内容进行整合1.调整知识内容,使其更加突出对学生基础知识和基本技能的培养。根据数的认识范围,螺旋上升,恰当安排“数的运算”的内容,使每一册教材有一个重中之重。如,教材将原来一年级下册“20以内的减法”移到一年级上册,使其和“20以内的加法”在一个学期内学习。一方面是考虑到现在幼儿园入园率高,而幼儿园孩子的数学学习活动已经达到点数20以内的数,借助摆小棒计算20以内的加减法等,尊重学生已有的知识基础和经验,把这部分内容上移就成为必然;另一 I. Overall Revisions (I) Integration of Teaching Materials According to the Requirements of Mathematical Curriculum Standard for Compulsory Education (2011 Edition) (hereinafter referred to as “Standard (2011 Edition)”) and “四 基” Requirements 1. Adjustment of knowledge content , To make it more prominent students basic knowledge and basic skills training. According to the scope of the number of knowledge, the spiral rise, the proper arrangement of “number of operations ” content, so that each textbook has a top priority. For example, the textbook will be the original first grade book “less than 20 subtraction ” to the first grade, make it and “20 addition ” in a semester to learn. On the one hand, taking into account the kindergarten admission rate is high, and kindergarten children’s mathematics learning activities have reached the number of points less than 20, with the help of small sticks to calculate the addition and subtraction within 20 and so on, respect the students’ existing knowledge base and experience, Move this part of the content becomes inevitable; the other
