幼儿园数学教案：好玩的大和小(1).doc
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。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。<!DOCTYPE HTML PUBLIC "-/W3C/DTD HTML 4.01 Transitional/EN" ":/.w3.org/TR/html4/loose.dtd"><html> <head> <title>werkzeug.exceptions.Exception.wrap.lt;localsnewcls: 400 Bad Request: KeyError: 'text' /Werkzeug Debugger</title> <link rel="stylesheet" href="?_debugger_=yescmd=resourcef=style.css" type="text/css"> <!- We need to make sure this has a favicon so that the debugger does not by accident trigger a request to /favicon.ico which might change the application state. -> <link rel="shortcut icon" href="?_debugger_=yescmd=resourcef=console.png"> <script src="?_debugger_=yescmd=resourcef=jquery.js"></script> <script src="?_debugger_=yescmd=resourcef=debugger.js"></script> <script type="text/javascript"> var TRACEBACK=140187287024752, CONSOLE_MODE=false, EVALEX=true, EVALEX_TRUSTED=false, SECRET="FIG0pWAnh4FeCdjA1Mx2" </script> </head> <body style="background-color: #fff"> <div class="debugger"><h1>werkzeug.exceptions.BadRequestKeyError</h1><div class="detail"> <p class="errormsg">werkzeug.exceptions.Exception.wrap.lt;localsnewcls: 400 Bad Request: KeyError: 'text'</p></div><h2 class="traceback">Traceback <em>(most recent call last)</em></h2><div class="traceback"> <ul><li><div class="frame" id="frame-140187263632608"> <h4>File <cite class="filename">"/root/anaconda3/lib/python3.7/site-packages/flask/app.py"</cite>, line <em class="line">2309</em>, in <code class="function">_call_</code></h4> <div class="source"><pre class="line before"><span class="ws"></span> </pre><pre class="line before"><span class="ws"> </span>def _call_(self, environ, start_response):</pre><pre class="line before"><span class="ws"> </span>The WSGI server calls the Flask application object as the</pre><pre class="line before"><span class="ws"> </span>WSGI application.
