数学模型是用数学语言概括或近似地描述现实世界事物的特征、数量关系和空间形式的一种数学结构.数学模型不仅为数学表达和交流提供有效途径,也为解决现实问题提供重要工具,可以帮助学生准确、清晰地认识、理解数学的意义.在小学数学教学中,教师应采取有效措施,通过数学建模真正体会数学的应用价值,培养学生用数学意识以及分析和解决实际问题的能力.一、在“削足适履”前能“对号入座”———在具体情境中感
Mathematical model is a mathematical structure that summarizes or approximates the features, quantitative relations and spatial forms of real world things in mathematical language.Mathematical models not only provide an effective way for mathematical expression and exchange, but also provide important tools for solving practical problems, To help students understand and understand the meaning of mathematics accurately and clearly.In the elementary mathematics teaching, teachers should take effective measures to truly understand the application value of mathematics through mathematics modeling, cultivate students’ ability of using mathematical consciousness and analyzing and solving practical problems.
