1、Unit5Unit5 HeightHeight andand WeightWeight (北师大版小学英语(北师大版小学英语 6 6 年级上)年级上) Lesson 2 Lets practice 一、内容分析一、内容分析 本单元以测量身高、体重为主要话题,引出形容词的比较级、最高级这一语 法现象。通过课本中设计的几部分不同层次的活动,使学生逐步掌握本单元的主 要功能句型,并能在真实情景中初步运用。通过练习,进一步巩固形容词的比较 级、最高级的形式变化规律。 本课时为第二课时,学生在第一课时中主要学习了课文部分,在课文中初步 接触到了询问身高、体重的句型及形容词比较级和最高级;而本课时的重点则
2、放 在帮助学生灵活运用所学语言,掌握形容词比较级、最高级的变化形式,培养学 生综合运用语言的能力。 二、学情分析二、学情分析 经过了三年半英语的学习,六年级学生的英语水平已经有了一定的基础,但 是随着知识难度的增加,学生的两极分化也越来越显现,因此就更要求教师在设 计教学环节上要有创新,依然要把学生的学习兴趣放在首位。而本课时涉及到的 一些内容,如形容词,学生在四年级的时候就已经接触过,虽然没有接触到比较 级和最高级,但是对于相对简单一些的形容词,学生掌握起来还是比较容易的, 这样在本节课的学习中, 教师通过前面单词的铺垫很容易带到今天新知识的学习 之中。 三、设计思路三、设计思路 以 Ann
3、、Ken 带 Mocky 去 town center 为主线。以 Look and Say 为依托,通过 学生复习故事方式导入新课,既复习了旧知识,又很自然的为新课做好了铺垫。 让学生在很轻松的学习氛围中进入状态,而在此过程中让学生动脑思考,行动参 与,一下子拉近了和老师的距离,使他们很轻松地参与到课堂教学中。 在随后的教学中,在各种情景中,引入 learn to say 的形容词,学生感知体验 比较级和最高级,再通过布置任务,让学生调查同学的身高、体重: “How much do you weigh? How tall are you?”通过表格对比,由组长或其他同学综合语言转 述小组情况。
4、 通过小组合作学习的方法,让学生在小组中体验互助学习的快乐, 也使学生在小组学习中锻炼自己的表达能力。然后利用歌曲中的图片,引导学生 在 PPT 帮助下,对比图片,运用比较级和最高级,接着利用图表直观地呈现形 容词的比较级、最高级的构成。最后由学生发现、归纳、总结,体现学生为中心 的教学原则。 四、教学目标四、教学目标 (一)能够在实际情境中询问他人有关身高、体重的问题; (二)能够比较人物的身高、体重; (三) 能够掌握并运用以下形容词big, small, short, long,old, young, heavy , thin 的 比较级和最高级;对人或事物外形比较; (四)在学习中对形

Write down the words with “er”and “est”.完成练习 2 Ok,look at the blackboard,todays winner is G1,congratulations. 反思:1.学生学习的重点涉及了比较级、最高级这一语法现象,我在前面的教学 铺垫中让学生初步理解并使用,学生很好地感知理解了这两个概念。课前创设了 情景,了解师生信息,师生互问答;之后串联情景,将各个板块自然衔接。 2.考虑到借班的六年级学生害羞,思维不是很活跃,我设计时预设了可能会出现 的问题,于是为学生提供了足够的语言支撑点,例如表格和结尾的 Lets talk. 3.有的环节问答时间过于拖长了,导致后面的 Lets talk 环节有点赶。而且总 结形容词比较级和最高级的规律稍显仓促。 4.板书设计应该图片搭配,这样便于学生理解。而且最高级的句型应该及时上黑 板。
