执教者：武汉市育才小学 姜瑞欣

教学内容：西南师大2011课标版小学数学三年级上册第七单元例题5

教学目标：

1．通过学生自主探究，加深对周长含义的认识，进一步巩固长方形、正方形周长的计算方法，探索拼组图形时四边形周长的变化规律，并能应用规律解决简单的实际问题。

2．引导学生经历解决问题的全过程，培养观察能力、操作能力、透过表象分析事物本质的能力，积累解决问题的策略和数学活动经验。

3．在探究活动中，发展学生的数学思维和几何直观，培养空间观念。

教学重点：探索拼组图形时四边形周长的变化规律。

教学难点：不断完善规律并应用规律解决问题。

教学准备：多板、ppt课件、平板电脑（学生每人一个）、学习单。
