    主题 三位数除以一位数(二)教学反思

      当堂课的教学任务不能完成是我上学期最头疼的一件事,所以解快这个问题是本学期的一个重要任务。鉴于这方面的思考,今天的首位不能整除的三位数除以一位数的笔算.的教学作了一些调整,效果比以前好多了。
      整个教学过程是这样的:首先复习了昨天学习的知识,让学生笔算了496÷4,然后由情境图引出了312÷4的教学。让学生在观察的基础上,判断商是几位数,并说出是怎么判断的,很自然的让学生尝试其的竖式计算,在学生尝试完成后,让学生交流各自的计算,提取了计算的注意点后,让学生比较复习题和新授题的不同点和相同点,最后引导验算比较.
      新授结束后,进行巩固练习.整个巩固练习没有像以前那样让每个孩子把每道题目都完成,像想想做做的第二题让左边两组的学生做一二两题,右边两组的学生做三四两题;第三题是这样处理的,先让每个学生判断商是几位数,是怎么判断的,然后第大组选取相应的一组题完成.这样处理不仅完成了教学任务,也能让学生在评讲中感受不题目的区别,更能赢得时间很好的发现了第四题题中隐含的规律,也完成了想想做做的第5题和第6题,也完成了今天所有的教学任务.
      今天的教学让我明白,教学中也是要有所"放弃"才能有更多的"收获".
