模型思想是数学的基本思想之一。模型的产生、发展、形成的过程,是数学知识体系建立、发展和完善的过程,也是学生数学学习展开、推进、提升的过程。二年级下册“两步计算的加减法实际问题”内容的教学,基于模型思想,让学生经历自主发现问题、提出问题、分析问题、解决问题的学习过程,掌握数学思考方法,感悟数学模型思想。
Model idea is one of the basic ideas of mathematics. The process of the generation, development and formation of a model is the process of establishing, developing and perfecting the mathematical knowledge system, as well as the process of developing, promoting and improving the mathematics learning of students. The second grade under the book “two-step calculation of the actual problem of addition and subtraction, ” teaching content, based on the model of thinking, allowing students to experience autonomy found problems, ask questions, analyze problems, solve the problem of learning process, master mathematical thinking, perception Mathematical model thinking.
