一、新教材的亮点1.调整编排,更为合理,利于教与学。以“万以内加减法”为例,新版教材在实验版教材的基础上有所调整和改进。这样的编排,循序渐进、逻辑性强,改变以往跳跃性较强的不足,降低难度,减缓了教学的坡度。又如,改变实验教材集中教学加减法“验算”的编排方式,将加减法的验算安排在教完某一类型计算后紧接着进行,即分散出现。这样编排,可以利用验算的教学及时巩固学生新学的笔算知识,有利于学生体会验算的作用。而“多位数乘一位数”的教学,先从简单的口算入手,然后笔算,笔算又分不进位、进位和连
First, the highlights of the new textbook 1. To adjust the orchestration, more reasonable, conducive to teaching and learning. To “million within plus and minus ” as an example, the new textbook experimental version of the textbook based on the adjustment and improvement. Such arrangements, step by step, strong logic, changes in the past strong lack of jumping, reducing difficulty, slow down the slope of teaching. Another example is to change the experiment teaching material concentrated teaching addition and subtraction “checking ” arrangement, the addition and subtraction method of checking calculation arranged in the teaching of a certain type of calculation followed immediately, that is scattered. This arrangement can make use of checking the teaching of new students in a timely manner to consolidate the pen knowledge, is conducive to students experience the role of checking. The “multi-digit by one number ” teaching, starting with a simple mouth start, and then calculate, pen and not divided into bits, carry and even
