进位加法和退位减法一直都是小学低段教学的重点,也是教学的难点。一直以来,都是学生进一步学习的拦路虎;教师在教学过程中一直会用较大的力气和较多的教学时间去对学生予以强化训练,但是对学习能力较差的学生来说收效甚微,这就给我们教师进行的其他教学活动带来极大的不便,造成学生在计算能力方面的发展存在很大的缺陷,如何避免这样的事情发生呢?成为我们教师必须思考的重要课题。有没有解决这一教学重点和难点的方法呢?经过我长期的教学实践和研究,答案是肯定的。现在我就把我在教学中的这一创新在这篇文章中教给大家,以方便大家在今后的教学中加以应用。

All along, teachers are stumbling block to further learning; teachers in the teaching process will always use more energy and more teaching time to strengthen the training of students, but poor learning ability for students with little effect, This brings great inconvenience to other teaching activities conducted by our teachers, resulting in great deficiencies in the development of students’ computing abilities. How to avoid such a thing? It has become an important issue that our teachers must think about. There is no solution to this teaching key and difficult way? After my long-term teaching practice and research, the answer is yes. Now I put my innovation in teaching in this article to teach you to facilitate the application in the future teaching.
