前不久,笔者参加了本市一所学校的课题研究成果展示课活动,一位老师执教人教版二年级上册的“观察物体”一课。她将教材中的恐龙玩具材料换成了每面贴有不同动物图案的正方体,学生分成8~10人一组开展活动,其中有这样一个片段。师(拿出给学生准备的正方体):小朋友们,这是什么?生:这是一个正方体。师:对了,这是一个正方体,每面都贴有不同的动物图案。请将老师准备好的正方体放在桌子中间,都面对着正方体坐好。如果我们把贴有长颈鹿的这一面看作前面,请想一想,你坐在了正方体的什么面?几个学生分别高兴地说出了自己坐的位置:左面、右面、后面、前面。
Not long ago, I participated in a city school project research results show class activities, a teacher taught PEP second grade “observation object ” class. She replaced the dinosaur toy material in the teaching materials with cubes with different animal patterns on each side. The students were divided into groups of 8 to 10 people to carry out activities, including such a fragment. Teacher (take out the square prepared for students): Children, what is this Health: This is a square. Teacher: Yes, this is a cube with a different animal pattern on each side. Please put the teacher prepared square in the middle of the table, are facing the cube sitting. If we think of this side with the giraffe as the front, think about what you were sitting on the cube. Several students were happy to say where they were sitting: left, right, back, front.
