数形转化,是指把数、形问题从一种表示形态转化成另一种表示形态或数形相互转化的思想和方法。它是数学教学中一种十分重要的解题策略。在小学数学教学中,主要表现为数的转化、形的转化、数与形的相互转化等三种具体形态。数形转化与解题关系密切。从某种意义上讲,解题的过程就是依据一定的规则使问题由难 Numeric transformation refers to the idea and method of translating numbers and shapes from one form of representation to another, or the transformation of forms from one form to another. It is a very important problem-solving strategy in mathematics teaching. In primary school mathematics teaching, the main performance for the number of transformation, the transformation of form, the transformation of number and form of three specific forms. Number conversion and problem solving are closely related. In a sense, the process of problem solving is based on certain rules that make things difficult
