《小学数学课程标准(2011版)》(以下简称新课标)提出十个核心关键词,其中就专门提到培养学生的模型思想。很多教师对数学建模的意思不理解,感觉很深奥,这里有必要再重述一遍。《新课标》指出:“建立和求解模型的过程包括:从现实生活或具体情境中抽象出数学问题,用数学符号建立方程、不等式、函数等表示数学问题中的数量关系和变化规律,求出结 ”Primary Mathematics Curriculum Standard (2011 Edition)“ (hereinafter referred to as the new curriculum standard) put forward ten core key words, which specifically mentioned to cultivate students’ model thinking. Many teachers do not understand the meaning of mathematical modeling, I feel very esoteric, it is necessary to repeat it here. The New Curriculum Standard states: ”The process of establishing and solving a model includes abstraction of mathematical problems from real life or concrete situations, mathematical relations such as equations, inequalities, functions, etc., Find the knot
