【背景】数学模型是联系数学与现实世界的桥梁。引导学生建构数学模型的过程,既是数学化的过程,也是思维训练的过程,这有助于他们发现数学,“创造”数学,提高运用数学的能力。对于小学来讲,数学模型是遥不可及,还是揠苗助长?是无意插花,还是有意栽树?这需要我们进行实践的探索与思考。下面就苏教版四年级(下)“乘法分配律”片段为例进行教学实践。
【Background】 Mathematical model is the bridge linking mathematics with the real world. The process of guiding students to construct mathematical models is not only a process of mathematics but also a process of thinking training, which helps them discover mathematics, create mathematics and improve their ability to use mathematics. For elementary schools, is the mathematical model out of reach, or is the seedlings contributing? Is it not intended to flower arrangements, or is it intended to plant trees? This requires us to explore and think in practice. Below the fourth edition of the Sujiao (second) “multiplication distribution law ” fragment as an example for teaching practice.
