英语人教版四年级上册Unit 1 B. Let's talk.Let's talk

UnitOneMyclassroom教学设计 (B. Lets talk )教学目标：1学生能够在情景中恰当运用句型LetsLetme提出行动建议并做出正确反应,以及其表示赞同的回答：Goodidea.和OK.并能在日常生活中区分和正确使用这两个句子来表建议和意愿。 2能听懂、会说cleantheclassroom,cleanthedesksandchairs,cleanthewindow,cleantheblackboard.并能在日常生活中用到这些表示动作的词组。3通过学习本课内容，教育学生要热爱班集体，热爱劳动。学情分析：我所带的四年级，大部分学生活泼好动，对英语有着极大的兴趣和热情，乐于参与游戏和比赛等有挑战性的活动，接受能力较强。但是也有少数学生基础较差，没有良好的听课习惯，需要多鼓励，多关注。本课主句型Lets贯穿于教材题目中，三年级就已接触过，应加强与新句型Letme的区别引导，让学生真正理解所学。教学重点：1.学生能够在情景中恰当运用句型LetsLetme提出行动建议并做出正确反应;2.学习词组cleantheclassroom,cleanthedesksandchairs,clean the window,cleantheblackboard.教学难点：1.区分和正确使用Lets与Letme 2.clean在本课中具有两种含义，教师要在学生不理解时进行解释。教具准备：教学课件Unit1LetstalkB教学过程：Step1Warm-up&revision1)Freetalk.T：How are you today？Ss: Im fine , thank you./Thanks2)Revision :-Lets go to school.
