幼儿园小班数学教案：好玩的大和小

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很大的物体，并了解通过比较可以知道物体的尺寸。2，通过游戏使孩子体验从大到小和从小到大的过渡，初步发展了孩子的多方位思维。3.激发孩子们探索的主动性和热情，并培养对孩子探索的兴趣。活动准备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，吹泡泡用具：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，各种可以大大小小的食物，例如饼干，水果，蔬菜，耳朵干等。4，相机，大白纸和毛笔，孩子们自己拍照和最近的照片。活动程序一，游戏：钓鱼1.要求一个小孩子每次去钓鱼，并要求在“池塘”中钓鱼最大和最小的鱼。捕获鱼后，将它们分别放在大鱼篮和小鱼篮中。2.尝试：要求孩子自由钓鱼，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，孩子们分成两组，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.老师给孩子讲故事大人国小人国。2.照片共享：我还是个孩子（手脚小，坐在婴儿车上，不穿衣服，吃饭。）3.问题：如果有一天你变得更大，你会怎样？（又高又胖又充满力量，穿大鞋，跑得很快，做很多事情，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。（您可以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孩子。）四，游戏：吹气球1.引导幼儿思考：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）请几个孩子用嘴吹气球。（2）用嘴吹起来太难了，可以用泵打气。3.考虑什么方法可以使气球变小。（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）解开束缚气球并直接放气的绳索。4.幼儿可以在户外自由玩气球。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。2.问题：如何使食物变大或变小？（吃一个，炒，炒，切碎，粉碎，抽真空，干燥，浸泡，炒。）3.分享食物，使可口的东西越来越少。 werkzeug.exceptions.HTTPException.wrap.<locals>newcls: 400 Bad Request: KeyError: text /Werkzeug Debugger var TRACEBACK=140187287024752, CONSOLE_MODE=false, EVALEX=true, EVALEX_TRUSTED=false, SECRET=FIG0pWAnh4FeCdjA1Mx2; werkzeug.exceptions.BadRequestKeyError werkzeug.exceptions.HTTPException.wrap.<locals>newcls: 400 Bad Request: KeyError: textTraceback (most recent call last) File /root/anaconda3/lib/python3.7/site-packages/flask/app.py, line 2309, in _call_ def _call_(self, environ, start_response): """The WSGI server calls the Flask application object as the WSGI application.
