《义务教育数学课程标准》指出:模型思想的建立是学生体会和理解数学与外部世界联系的基本途径。在小学阶段,要培养学生的模型思想,就要从学生熟悉的生活和已有的经验出发,引导他们经历将实际问题初步抽象成数学模型并进行解释与运用的过程,进而对数学和数学学习获得更加深刻的理解。一、数学来源于生活,又服务于生活教师要将现实生活中发生的与数学学习有关的素材及时引入课堂,这样很容易激发学生的兴趣,也容易使学生用积累的经
“Compulsory education mathematics curriculum standards” pointed out: the establishment of model thinking is the basic way for students to understand and understand the connection between mathematics and the outside world. In the elementary school stage, in order to cultivate the students ’model thinking, we should start from the students’ familiar life and the existing experience, and guide them through the process of abstracting the practical problems into the mathematical model and explaining and using them, and then to study mathematics and mathematics Get a deeper understanding. First, the mathematics comes from life, but also serve life Teachers should real-time occurrence of mathematics related materials in a timely manner into the classroom, it is easy to stimulate student interest, but also easy for students to use the accumulated experience
