全日制十年制学校小学课本《数学》第八册第一单元,介绍了“简易方程”的知识。这是我国小学数学教材的一项重要改革。我们知道,方程是解应用题的一个有力的工具。有些应用题,若限用算术方法来解,则颇为繁难。而用方程来解,就可以化难为易,化繁为简;并且,用方程解决的问题范围更加广阔。所以,应用题的方程解法,比算术解法更优越、更先进。随着科学技术和数学本身的不断发展,小学数学教学内容必须不断更新,用比较先进的教学内容替代比较陈旧的教学内容,这是发展的必然趋势。在小学数学教材中,引入“简易方程”的知识,正是顺应了这种趋势。为了帮助教师明确教学要求,深入理解和把握教材,本文拟介绍有关方程的初步知识,以供参考。
Full-time 10-year school primary school textbook “Mathematics” the first eight units, introduced the “simple equation” knowledge. This is an important reform of our primary school mathematics textbooks. We know that equations are a powerful tool for solving problems. Some application problems, if the use of mathematical methods to solve, it is quite complicated. The use of equations to solve, we can make it difficult for the easy to simplify; and, to solve the problem with a broader range of issues. Therefore, the application of the problem-solving equation, arithmetic solution than superior, more advanced. With the constant development of science and technology and mathematics, the content of primary mathematics teaching must be continuously updated, and the older teaching content should be replaced by more advanced teaching content, which is the inevitable trend of development. In primary school mathematics textbooks, the introduction of “simple equations” of knowledge, it is to follow this trend. In order to help teachers to clarify the teaching requirements and to understand and grasp the teaching materials in depth, this article intends to introduce the preliminary knowledge about the equations for reference.
