基于模型思想的小学数学单元教学设计

Unit Teaching Design of Elementary School Mathematics Based on Model Ideas

数学建模是数学核心素养之一,它在数学学习和应用的过程中逐步形成和发展。数学建模的本质是将现实问题数学化,它既是数学思想方法,也是一种数学活动。文章从单元教学的角度,将沪教版小学《数学》第六册第七单元“谁围出的面积最大”与“乘与除”的教学内容进行整合,基于模型思想开展单元教学,旨在激发学生的模型意识,体验模型思想,发展学生的创新精神和实践能力。

Mathematical modeling is one of the core competencies of mathematics,which is gradually formed and developed in the process of mathematics learning and application.Its essence is to mathematize realistic problems,which is not only a method of mathematical thought,but also a mathematical activity.From the perspective of unit teaching,this paper integrates the teaching content of Unit 7,Book 6(Shanghai Education Edition),“Who has the largest area”and“multiplication and division”,and carries out unit teaching based on model ideas,hoping to stimulate students'model consciousness,to help them experience model ideas and to develop their innovative spirit and practical ability.
