 详细教案咖\/：mxx55876 
 设计意图：
中班幼儿对海洋生物充满兴趣，对基本几何图形已有初步认知，为契合《3-6岁儿童学习与发展指南》科学领域数学认知目标，设计本次活动：以幼儿喜爱的海底世界为情境，将几何图形认知与海洋动物外形观察相结合，引导幼儿在趣味游戏中巩固图形特征，发现动物外形与图形的关联，通过动手拼搭提升图形组合与操作能力，同时激发幼儿对科学探究的兴趣，让幼儿在玩中学、做中学，实现认知、技能、情感的全面发展，感受数学与自然、生活的密切联系。
 活动目标：
1、认知目标：能够细致观察水母、热带鱼、海龟、海蟹等海洋动物的外形特征，准确找出与动物身体各部分形状相近的几何图形，并说出图形名称。
2、技能目标：能大胆尝试运用正方形、长方形、圆形、半圆形、三角形、椭圆形、梯形等多种几何图形，自主组合拼搭出完整的海洋动物，发展动手操作与空间想象能力。
3、情感目标：感受几何图形拼搭的乐趣，乐于参与集体游戏和动手操作活动，萌发对海洋动物、数学图形的探索兴趣。
 活动准备：
（一）经验准备：
幼儿前期已有用正方形、三角形等简单几何图形拼搭房子的基础经验，对圆形、三角形、正方形有初步认知。
（二）材料准备：
1、教具：海底世界主题背景板1块；水母、热带鱼、海龟、海蟹大型图形底板示范图片各1张；正方形、长方形、圆形、半圆形、三角形、椭圆形、梯形图形“门票”若干张。
 活动过程：
（一）情境导入：海底世界门票之旅。
1、教师创设情境，神秘导入活动主题。
2、教师随机分发几何图形门票，引导幼儿自主观察。
3、组织幼儿集体交流，鼓励幼儿大胆表达。
（二）探索感知：动物身上的图形秘密。
1、带领幼儿“走进海底世界”，引导幼儿观察主题场景和动物图片。
2、逐一出示海洋动物图片，分层引导幼儿探索。
3、鼓励幼儿分组讨论，大胆说出自己的发现
4、教师小结：原来这些可爱的海洋动物，都是由各种各样的几何图形组成的，图形组合在一起就能变出不一样的小动物。
（三）动手操作：拼搭我的海洋朋友。
1、教师提出操作要求：用几何图形，拼出自己最喜欢的海底小动物。
2、幼儿分组动手操作，教师巡回指导。
3、幼儿进行作品展示分享。
4、教师简单点评，对幼儿作品进行表扬，肯定每一位幼儿的作品，增强幼儿自信心。
