数学建模是学生用数学工具解决实际问题的重要手段之一。“就许多小学数学内容而言,本身就是一种数学模型……我们每堂课都在建立数学模型。”(张奠宙语)帮助学生积累数学活动经验,是《义务教育数学课程标准(2011年版)》中的“四基”要求之一。因此,教师不仅要引导学生构建数学模型,还要帮助学生不断积累数学建模活动经验。所谓数学建模活动经验,就是学生从已有生活经验、知识经验和
Mathematical modeling is one of the most important tools for students to solve practical problems with mathematical tools. “For many elementary school math content, it is a mathematical model in its own right ... We have mathematical models in each class. ” (Zhang Xian Chaoyu) to help students accumulate experience in math activities, is the compulsory education mathematics curriculum standards (2011 Year Edition) “in the” four base "one of the requirements. Therefore, teachers should not only guide students to build mathematical models, but also help students accumulate experience in mathematical modeling activities. The so-called experience in mathematical modeling activities, that is, students from the existing life experience, knowledge and experience
