1、幼儿园小班计算活动：了解图形活动目标：1.初步了解正方形，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准备：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老师：孩子们，昨天，小白兔叫老师。小白兔告诉老师她的房子坏了。请老师给她一间漂亮的新房子。您看到老师建造的新房子漂亮吗？小白兔子对老师说谢谢。2，显示图片，提问：老师：非常漂亮的房子！你看，老师把房子的门盖成什么形状？老师：真聪明！这房子的身体是什么形状？老师：我又猜对了。然后我想问你这房子的屋顶是什么形状？老师：孩子们真的很聪明，他们都是正确的，我们的
2、图形婴儿也很强大。三角形可以用作房屋的屋顶。方形婴儿可用作房屋的主体，圆形婴儿可用作门。孩子们，我们将来会用图形婴儿来盖房子！今天，老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，孩子可以知道正方形对孩子有一定的困难，孩子们称其为正方形婴儿。在游戏中，由于孩子准备了用于孩子操作的材料，因此当孩子进行操作时，材料似乎很拥挤。 werkzeug.exceptions.HTTPException.wrap.<locals>newcls: 400 Bad Request: KeyError: text /Werkzeug Debugger var TRACEBAC
