【摘要】:長方體的認識,一般的教學流程都是讓孩子們準備好一個長方體和一個正方體,課堂上自己動手數(shù)一數(shù)、量一量,記錄好長方體和正方體的特征后小組交流再全班交流長方體的特征。接著認識長方體的長寬高,知道正方體是長寬高都相等的特殊長方體。本案例設計了課前預學環(huán)節(jié),試圖引導學生通過自學來認識長方體的特征,上課直接檢查預習情況,把更多的時間留給學生去動手實踐、獨立思考、合作交流,使學生獲得廣泛的數(shù)學活動經(jīng)驗,激發(fā)學生的學習熱情,培養(yǎng)其探究能力和自主學習的意識。
[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.
