这是笔者上的一节随堂课,内容是五年级下册第三单元《长方体和正方体》,前面学生学习并理解了长方体和正方体的表面积,为了进行检测、巩固和提高,笔者将《练习六》作为载体,通过训练和反馈,以达到预期的效果。涉及这一知识的题目有一个特点:列式繁琐,计算量大。本节课的教学任务是完成练习六的9个应用题,并完成课堂作业本。为了完成这一艰巨任务,我怀着焦急的心情,催学生抓紧时间完成练习,又用快得让人觉得任何一个学生都是天才的速度把结果讲解一遍,其实我已经能隐约感觉到学生木讷的表情,知道这是无法接受的信 This is a section of the author on the class, the content is the third unit of the fifth grade Volume “cuboid and cube”, in front of students learn and understand the cuboid and cube surface area, in order to detect, consolidate and improve, I will “practice Six ”as a carrier, through training and feedback, in order to achieve the desired results. A topic related to this knowledge has a characteristic: column type cumbersome, computationally intensive. The teaching task of this lesson is to finish 9 application questions of Exercises 6, and finish the homework of the class. In order to accomplish this arduous task, with anxious mood, urge students to seize the time to complete the practice, and quickly make people feel that any one student is a genius speed to explain the results again, in fact, I have been able to vaguely feel the students stiff The expression, know this is unacceptable letter
