浅谈如何在小学数学课堂教学中渗透数学模型思想——以《植树问题》为例

How to infiltrate mathematical model into primary school mathematics teaching——Take tree planting as an example

数学模型思想不仅有利于学生提高归纳总结的能力、形成举一反三的思想意识,而且对于提高学生分析问题、解决问题的能力也有着巨大的作用。《数学广角》是人教版数学教材为了渗透数学思想而专门编排的内容,下面笔者以人教版五年级上册的数学广角《植树问题》为例,浅谈如何渗透模型思想。

The thought of mathematical model not only helps students improve their ability of induction and summary,but also plays an important role in improving students’ ability to analyze and solve problems. "Mathematics wide angle" is the content specially arranged by the people’s education press in order to infiltrate mathematical ideas. The following author takes the mathematical wide angle "tree planting problem" in the first volume of the fifth grade of PEP as an example to discuss how to infiltrate the model idea.
