转化思想是数学思想的重要组成部分。它是从已知领域发展,通过数学元素之间向未知领域转化,将未知的、陌生的、复杂的问题通过演绎归纳等方法转化为已知的、熟悉的、简单的问题,从中找出它们之间的本质联系,解决问题的一种思想方法。在小学高年级数学中,许多新知识的形成是随着新问题的解决而产生的,我们一般是将复杂问题转化为简单问题,将难解问题转化为易解问题,将未解问题转化为已解问题,将抽象问题转化为直观问题, Transformation thinking is an important part of mathematical thought. It is from the development of known areas, through the conversion of mathematical elements to unknown areas, the unknown, strange, complex problems by deductive induction and other methods into known, familiar, simple, find them The nature of the relationship between the solution to the problem of a way of thinking. In the upper elementary mathematics, the formation of many new knowledge is generated with the solution of new problems. We generally convert complex problems into simple ones, translating difficult ones into easy ones, and unresolved ones into Solved the problem, the abstract problem into an intuitive problem,
