1、幼儿园小班计算活动：理解图形活动目的：1.初步理解正方形，三角形和圆形之间的区别2.培养幼儿参加活动的积极性活动预备：纸路（以不同形状和尺寸显示），具有多个几何形状和不同形状的“魔术盒”，白兔唱片，一栋组合房屋活动内容：1.讲故事引起幼儿的兴趣教师：小孩们，昨天，小白兔叫教师。小白兔告诉教师她的房子坏了。请教师给她一间美丽的新房子。您看到教师建造的新房子美丽吗？小白兔子对教师说感谢。2，显示图片，提咨询：教师：特别美丽的房子！你看，教师把房子的门盖成什么形状？教师：真聪明！这房子的身体是什么形状？教师：我又猜对了。然后我想咨询你这房子的屋顶是什么形状？教师：小孩们确实特别聪明，他们都是正确的，

2、我们的图形婴儿也特别强大。三角形能够用作房屋的屋顶。方形婴儿可用作房屋的主体，圆形婴儿可用作门。小孩们，我们今后会用图形婴儿来盖房子！今天，教师会带你去找一个图形宝宝玩游戏吗？活动反思：在识别图形，三角形，圆形后，小孩能够明白正方形对小孩有一定的困难，小孩们称其为正方形婴儿。在游戏中，由于小孩预备了用于小孩操作的材料，因而当小孩进展操作时，材料大概特别拥堵。 werkzeug.exceptions.Exception.wrap.lt;localsnewcls: 400 Bad Request: KeyError: text /Werkzeug Debugger var TRACEBACK=14
