1背景介绍“面积”是数学新课程标准确定的重要的数学学习内容之一。新课程标准要求让学生经历、体验对面积含义的认识、面积单位的认识与简单换算、面积公式的发现以及运用这些知识点解决一些简单的实际问题的过程。而“面积”对于小学三年级学生来说,是一个比较难理解的概念。因此,体验、经历和设计一些有关面积的实践活动是面积学习的首要目标。练习课的内容设计也就针对这些知识点展开,练习量也根据学生的情况相应增多了一些。
1 Background Introduction “Area ” is one of the important mathematical learning topics identified by the new curriculum standard in mathematics. The new curriculum standard requires students to experience and experience the understanding of the meaning of area, the understanding and simple conversion of area units, the discovery of area formulas, and the process of using these points of knowledge to solve some simple practical problems. The “area ” for the third graders, it is a more difficult to understand the concept. Therefore, experiencing, experiencing and designing some area-related practical activities is the primary goal of area learning. The content of the practice lesson is also designed for these knowledge points to start, the amount of practice is also a corresponding increase in the number of students.
