本文以《乘法分配律》的教学为例,谈谈在教学中如何渗透数学模型思想。从现实生活或具体情境中抽象出数学问题在教学《乘法分配律》时,我创设了两个游戏:第一个是来自学生身边济青高速公路上的相遇问题:两辆汽车分别从济南和青岛相对开出,大巴车每小时行110千米,中巴车每小时行90千米,两小时后相遇。第二个是小强摆木块的游戏:每行摆6个绿木块,8个红木块,共摆了4行。两个游戏使学生置身于非常熟悉的生活和
This article takes the teaching of “Multiplication Assignment Law” as an example to talk about how to infiltrate the idea of mathematical model in teaching. Abstraction of Mathematic Problems from Real Life or Specific Situations In teaching “Multiplication and Distribution Law”, I created two games: The first one came from Jiqing Expressway on the side of the students: two cars from Jinan and Relatively out of Qingdao, the bus line 110 kilometers per hour, bus line 90 kilometers per hour, two hours later meet.
