课标理念
课标要求学生在学习梯形的面积时,要在已有认识梯形的底和高的基础上,经历探索梯形面积计算方法的过程,并能运用面积计算公式解决生活中一些简单的问题,并在探索图形面积的计算方法中,获得数学探索的经验。
","type":1},{"audio_music_id":0,"source":0,"text":"教材分析
本课是在学生认识了梯形的特征,并掌握了长方形、正方形、平行四边行和梯形的面积计算,并形成一定的空间观念的基础上进行教学的。因此教材没有安排数方格的方法求梯形的面积,而是直接给出一个梯形,引导学生想,怎样仿照求三角形面积的方法,把梯形转化成我们已经学过的图形来计算它的面积,让学生主动参与探索的过程,发现并掌握梯形的面积计算方法,让学生在教学的再创造过程中实现对新知识的构建,解决新问题,获得新方法。

五年级的学生,善于独立思考,乐于合作交流,语言表达能力较强,十分愿意发表独立见解,有较好的学习数学的能力,他们已经掌握了梯形的特征和长方形、三角形以及平行四边形的面积计算方法,也学习了图形的旋转平移的方法。这些都为本节课的学习奠定了坚实的基础。
