1、幼儿园小班数学教学计划：大大小小的乐趣1.学会视觉上测量尺寸差异非常大的物体，并理解通过比拟能够明白物体的尺寸。2，通过游戏使小孩体验从大到小和从小到大的过渡，初步开展了小孩的多方位思维。3.激发小孩们探究的主动性和热情，并培养对小孩探究的兴趣。活动预备1.有20条硬纸鱼（大小不一），数根钓鱼竿和一个带“池塘”的大池塘。2，吹泡泡器具：用肥皂水的塑料瓶，一根吸管（单孔，多孔，厚度不同）多于儿童，气球。3，各种能够大大小小的食物，例如饼干，水果，蔬菜，耳朵干等。4，相机，大白纸和毛笔，小孩们本人拍照和最近的照片。活动程序一，游戏：钓鱼1.要求一个小小孩每次去钓鱼，并要求在“池塘”中钓鱼最大和最小

2、的鱼。捕获鱼后，将它们分别放在大鱼篮和小鱼篮中。2.尝试：要求小孩自由钓鱼，但仍要求最大和最小的鱼。二，游戏：超胜一。1.请用望远镜将手放在眼睛前面。让我们在教室里找到“大”和“小”。2，小孩们分成两组，玩多于一个游戏：谁是最大的鞋子？谁的头最大？谁的嘴最大？谁的手最大？谁穿得最多？三，游戏：成人与反派1.教师给小孩讲故事大人国小人国。2.照片共享：我依然个小孩（手脚小，坐在婴儿车内，不穿衣服，吃饭。）3.咨询题：假如有一天你变得更大，你会怎么样？（又高又胖又充满力量，穿大鞋，跑得非常快，做非常多事情，上学，等等）4.激发幼儿运用想象力来表达身体特定部位的变化。幼儿的身体轮廓印在纸上。（您能够

3、张开双臂并分开双脚来表示一个成年人；使用腋窝，手臂，腿和脚来收紧或捡起牙齿来表示您的小孩。）四，游戏：吹气球1.引导幼儿考虑：会变得越来越大的物体是什么？（游泳圈，气球，蹦床，折叠床，风扇，被子，雨伞。）2.幼儿尝试使气球变大的方法。（1）请几个小孩用嘴吹气球。（2）用嘴吹起来太难了，能够用泵打气。3.考虑什么方法能够使气球变小。（1）使用身体部位（用手戳，用脚炸开并用屁股踩碎）。（2）通过外力（用针折断，用锤子或砖头砸碎，用钉子刺穿）（3）解开束缚气球并直截了当放气的绳索。4.幼儿能够在户外自由玩气球。五，游戏：食物变化1.每个人围坐在桌子旁，观察饼干，水果，蔬菜，火腿，木耳，面粉和其他食物

4、。2.咨询题：如何使食物变大或变小？（吃一个，炒，炒，切碎，粉碎，抽真空，枯燥，浸泡，炒。）3.分享食物，使可口的东西越来越少。 werkzeug.exceptions.Exception.wrap.lt;localsnewcls: 400 Bad Request: KeyError: text /Werkzeug Debugger var TRACEBACK=140187287024752, CONSOLE_MODE=false, EVALEX=true, EVALEX_TRUSTED=false, SECRET=FIG0pWAnh4FeCdjA1Mx2; werkzeug.exceptio
