1、unit4Itswarmtoday第三课时PEP小学英语四年级Unit4Its warm today教学设计 (第三课时)一、教学目标学生能听、说、认读 sunny, cloudy, windy, rainy, snowy，并能通过探究，掌握这几个词汇读音规律。学生能够了解不同天气的形成过程，并初步学会根据自然界的各种现象判断天气即将发生的变化。二、教学内容分析：本课的内容是与我们生活息息相关的天气的话题。教师能够就当时教室内的温度引出warm一词。然后向学生播放一段英文讲解的天气预报的实录，从而引出weather report，同时让学生感受一下描述气候的语句。三、教学难点分析：单词weat

2、her的发音；Can I wear my? 问答中的人称转换。四、教学过程教学过程设计说明热身（Warm-up）1. Lets do T： Walk, walk, walk, run , run, run. Fly, fly, fly. Jump, jump, jump . Dance, dance, dance. Swim, swim, swim.

8、li.T: Oh, light rain.b. Sing the song Rain, rain go away.学生的口中导出 rain 一词。教师在课堂中幽默的表演给课堂注入了新鲜的活力，借助学生的话渗透 heavy rain light rain。4. snow教师画冷空气板书：snowSs say the chant. SnowSnow, snow, where do you go?I dont know. I dont know.Where can I go?单词的操练形式可以灵活多样，Snow 一词的发音对学生来说较好掌握，因此通过一个朗朗上口的歌谣加以巩固。5. snowya.

11、课件二 不同天气图)学生在表达自己的思维的过程中，难免会出现一些语病，教师应加以鼓励，而非立即纠正,这正是学生从不自觉的模仿语言到自觉创造语言的良好开端。7. 用有节奏的 Chant 来操练Rainy rainy, run back home. Sunny sunny, play a game.Cloudy cloudy, rain is coming.在教师引导下自主探究语音规律得出sunny, cloudy, rainy这几个词的发音。拓展/巩固（Extension/Consolidation）活动 1T: (.课件三 晴天图) Its sunny. I can.T: (.课件四 阴天图)
