数学建模指采用形式化的数学语言对数量关系或空间形式进行抽象概括后的简约表达,是学生体会和理解数学与外部世界联系的基本途径。它揭示的是数学对象内在的数学关系结构,直接指向数学本质。由此而设计的教学,必然更能引发学生的深度思考。教材中相关素材比比皆是,教师若能恰当挖掘,巧妙渗透,就会让课堂充满思维的张力,显得更有数学味。以北师大版四年级下册《烙饼》为例,本课教
Mathematical modeling refers to the use of formal mathematical language to quantitatively summarize quantitative relations or spatial forms after the summary expression is the basic way for students to understand and understand the relationship between mathematics and the outside world. It reveals the mathematical relationship inherent in mathematical objects, pointing directly to the nature of mathematics. The design of the teaching is bound to better stimulate students to think deeply. Materials related materials abound, if teachers dig properly, ingenious penetration, it will make the classroom full of thinking tension, it seems more mathematical taste. To Beijing Normal University version of the fourth grade “pancake” as an example, this lesson teach
