【摘要】：长方体的认识,一般的教学流程都是让孩子们准备好一个长方体和一个正方体,课堂上自己动手数一数、量一量,记录好长方体和正方体的特征后小组交流再全班交流长方体的特征。接着认识长方体的长宽高,知道正方体是长宽高都相等的特殊长方体。本案例设计了课前预学环节,试图引导学生通过自学来认识长方体的特征,上课直接检查预习情况,把更多的时间留给学生去动手实践、独立思考、合作交流,使学生获得广泛的数学活动经验,激发学生的学习热情,培养其探究能力和自主学习的意识。
[Abstract]:In the knowledge of cuboids, the general teaching process is to make children prepare a cuboid and a cuboid, count and measure by themselves in class. After recording the characteristics of cuboids and cuboids, the group communicates with each other and the whole class communicates the characteristics of cuboids. Then, we know that cuboids are special cuboids with equal length and width, and that cuboids are special cuboids with equal length and width. It attempts to guide students to understand the characteristics of cuboids through self-study, to check the preparation situation directly in class, to leave more time for students to practice, to think independently, to cooperate and to communicate, so that students can gain extensive experience in mathematics activities. Stimulate students' enthusiasm for learning, cultivate their ability to explore and the awareness of independent learning.
