Lesson7Lesson7 -教学设计教学设计 一、一、 教学背景教学背景 教学教学年级：年级：四年级四年级 教教材分析：材分析： 本课是人教版精通英语四年级（下）第二单元的第一课时。本单元的主要话题是询问数 量多少,并正确使用数词来回答。本课是以翻转课堂的形式呈现的，由于数词的表达是有规律 的，并且整个单元的重点词汇就是百以内数词的表达，所以我在本课并没有按书中对本课时 的规划先学习 2129，而是制作微课，先将数词表达规律的视
2、频发到班级微信群，让学生在 家提前学习，再在课堂上进行总结归纳，引导学生通过已有知识来学习新知。在学生了解数 词的表达规律后，通过询问时间、出示计算题、归类游戏等方式进行练习数词的表达。学习 句子时，通过让学生巧妙的数苹果和球的数量来感受 How many 的含义，并询问所教班级有多 少个女生，多少个男生，再通过一道数学算式来得出班级内学生的数量。从而学习本课主要 学习内容： How many students are there in your class? There are并扩展句子 Are there? 以及 How many books are there on the desk?
3、学情学情分析：分析： 本课的教学对象是四年级的学生，这些学生从三年级开始学习英语，到目前为止已经学 习了近两年的时间，掌握了一定的英语知识，比如在三年级下册中学习了数词 112，在四年 级上册中学习了数词 1320，并且学生已经掌握了What time is it? Its以及 Whats and ? Its等句型。所以在本课的学习中不仅使用本课的重点句型How manyare there?There are来练习句子，还通过What time is it? Its以及 Whats and ? Its来操练数词的表达，然后再对本课重点句子进行替换问答，让学 生将知识融会贯通。 二、二、 教学目
