苏教版五年级数学图形单元复习课是在学生已经学完了多边形面积计算的基础上进行的,学生以前学习过长方形、正方形的面积,前几节课又学习了平行四边形和梯形面积的计算。复习课是小学课堂教学重要课型之一,其主要任务不单单是关注公式的整理和推导过程,还包括巩固、加深已学过的知识和培养空间想象能力、融会贯通能力,学生所要解决的知识是点、线、面三者的结合,它承载着回顾与整理、沟通与生长的独特功能。基于这样的考虑,我把本节复习课的教学设计进行了一些改变,
The fifth grade of the Sujiao Version of Mathematics Graphic Unit Review Course was conducted on the basis of the calculation of the area of the polygons already completed by the students. Before the students learned the area of the rectangle and the square, the previous sections also studied the calculation of parallelogram and trapezoid area. The review class is one of the important classes in primary school classroom teaching. Its main task is not only to pay attention to the process of formulating and deducing formulas, but also to consolidate and deepen the knowledge that has been learned and to cultivate the space imagination ability, mastery skills and students’ knowledge to be solved It is a combination of point, line and surface that carries the unique function of reviewing and organizing, communicating and growing. Based on this consideration, I made some changes to the instructional design of the review class in this section,
