一、课程标准相关要求及教材分析

本单元以“连续观察”为主题，语文要素是“体会文章准确生动的表达，感受作者连续细致的观察”。《爬山虎的脚》是统编教材四上的一篇观察描写植物的课文。作者是中国现代著名作家、教育家叶圣陶。叶圣陶在课文中用细致生动的文笔准确形象地介绍了爬山虎的叶子和脚的特点，并描写了爬山虎的脚是怎样爬上墙的，启发学生在生活中要留心观察身边的事物。

上节课，我们一起走进叶圣陶先生的文章里，去仔细观察了爬山虎的脚，还了解了它是怎样一脚一脚地往上爬的。那么爬山虎的叶子又是怎样的呢？

二、品读第二自然段，感受叶子特点：

1.默读第二自然段，说说叶圣陶爷爷笔下的爬山虎叶子给你留下了什么印象？

2.你发现叶老是怎么观察叶子的吗？

预设：观察了颜色的变化、分布排列。

3.这样细致的、多角度的观察，就让我们如同亲眼所见那满墙的叶子。你可以选择一句自己喜欢的句子，读给大家听。

指名学生读。

三、学习观察方法，拓展延伸。

预设：

l 叶尖一顺儿朝下，在墙上铺得那么均匀，没有重叠起来的，也不留一点儿空隙。

l 茎上长叶柄的地方，反面伸出枝状的六七根细丝，每根细丝像蜗牛的触角。

l 细丝原先是直的，现在弯曲了，把爬山虎的嫩茎拉一把，使它紧贴在墙上。

2.读读这些句子，你会发现，叶老先生之所以写得准确、形象，离不开---观察。

   而且是仔细观察，连续观察。你能结合自己摘抄的句子来谈谈吗？

3.出示（观察记录卡），你在观察时，还可以像这样及时做好记录。

4.我们课文后的资料袋里也有两种形式的观察记录，

（出示）一种是图文结合，一种是做表格。

小组合作：

（1）选择一种形式的观察记录进行讨论，看看需要记录哪些内容？

（2）交流讨论。

5.全班小结：

  图文结合：时间、天气、图片、观察到的现象。

  做表格：观察对象、时间、状态、颜色。

6.正是有了这样的记录，我们就能清楚地看到银杏种子的变化，了解到菊花开放的过程。

7.同学们可以在课后进行尝试，选一种植物，观察一段时间，试着用喜欢的方法，记录它的变化。你们一定能从观察中得到乐趣，也能写出准确形象的文字。

七、板书设计

10.爬山虎 的 脚          

     认真观察、长期观察  

做好观察记录
