数学的思想方法是人们从具体的数学问题中总结出来的对数学的本质性认识,是解决各种数学问题采取的手段和方法。而化归思想作为其中较为常见的一种方法,意为将遇到的没有解决的问题化为已经解决的问题,使问题化繁为简,是小学数学教学过程中较为重要的一种方法。本文结合现阶段小学数学教学的实际情况,联系化归思想的本质和作用,论述如何在教学过程中正确使用化归思想,开拓学生的思维,促进小学数学教学水平的提高。 The method of thinking and thinking of mathematics is the essential understanding of mathematics which people summed up from the concrete mathematics problem and is the means and method to solve various mathematical problems. As one of the more common methods, the thought of returning to the past means that the unresolved problems encountered are transformed into the problems that have been solved, and the problem is simplified. It is a more important method in the process of primary school mathematics teaching. Based on the actual situation of elementary mathematics teaching in present stage, this article discusses the nature and function of the thought of returning to normalization, expounds how to use correctly the thought of returning to normalize, to develop students’ thinking and promote the improvement of mathematics teaching in primary school.
