幼儿园数学教案：圆贴贴

幼儿园数学教案：圆形贴纸活动目标1.识别圆并使用圆创建样式。2.培养孩子的想象力和操作能力。活动准备1.各种彩色纸的大小圆圈。剪刀，纸，圆形贴纸，纸，磁铁，颜色等2，儿童数学书籍活动程序首先，讲故事并引起兴趣老师讲故事爱画画的波波的故事二，运用操作方法制作儿童拼图1.老师：请让孩子们成为Bobo，用圆形彩色纸粘贴拼贴贴纸，看看可以拼贴哪些形状。2.完成后，请让孩子们欣赏作品，并鼓励孩子们谈论他们用圆形拼贴做的事。三，带领孩子打开我的数学第一页激发孩子观察图片的内容，让孩子将喜欢的颜色涂到圆圈上。让我谈谈图片中的其他内容吗？四，引导孩子观察周围环境考虑一下，然后谈论生活中仍然存在的一切。故事：Bobo的故事，他喜欢绘画猪波波（Bobo）画了很多大小的圆圈。我的兄弟姐妹已经看了很长时间了。我不知道Bobo的圈子是什么。我问波波：你画的圆圈是什么？鲍勃说：“这个圈子里有两只手，一只长一只短，从早到晚转身。哥哥说：“哦，我知道了，这是时钟。”姐姐说：“这是什么？博博说：“它下面有一条长长的线。如果您想抓住它，就不会逃脱。我姐姐说，“嘿，这是一个气球”。我的兄弟姐妹终于知道了Bobo画了什么。 Bobo画了很多圆圈，甚至是肚脐眼的圆圈？妈妈说：“鲍勃真的是一位伟大的画家”。 werkzeug.exceptions.HTTPException.wrap.<locals>newcls: 400 Bad Request: KeyError: text /Werkzeug Debugger var TRACEBACK=140187291054992, 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.
