人教版四年级英语下册 Unit3 Weather Part A Let’s learn教学课件
Unit3 WeatherPart A Let’s learnAnalysis of the teaching contents:In this part, new words are cool, cold, hot, warm and weather. The teaching materials present the words describing the weather by a weather report which tells the temperature and weather condition of four main cities in China. Students are familiar with “hot”and “cold”which they have learned in the early grades. To do a weather report is a teaching key point for students.Analysis of the students:The fourth grade students can’t focus on a certain point for a long time. However, they have strong curiosity and competitive nature. I use various teaching methods to improve students’ activity and initiative.Teaching aims:Knowledge: Enable students to listen, speak and read new words: weather, cold, cool ,warm and hot.Ability: Enable students to use “It’s... in...”to introduce the weather in different places.Emotion: Cultivate students’ habit of watching the weather report. Enable them to put on or take off some clothes in time according to the weather report. Take care of themselves and their families.Teaching important points:1.New words: weather, cold, cool, warm and hot.2.To use “It’s... in...” to describe the weather in different places. Teaching difficult points:1. The pronunciation of warm, cool and Hong Kong.2. Enable students to do a weather report expertly.Teaching aids:Word cards, a bottle of warm water, a hat and CAI.Teaching methods:TPR and task-based approach.Teaching procedures:Step1 Greetings (2 minutes)T: Good morning, boys and girls. It’s my first time to be here. So you don’t know me. Let me tell you. My name is Candy. So you can call me Candy. Let’s say hello again. Hello, boys and girls.Ss: Hello, Candy.Step 2 Warm up and lead in. (3 minutes)1.Free talkT: I’m an English teacher. Do you like English?Ss: Yes.T: I like English very much. I can sing many English songs.2.Lead inI sing an English song “ How’s weather?”T: How’s weather today? Cold? Hot? Warm?Ss:...Lead in the title of Unit3 Weather.( It aims to get close to new students and raise their interests in learning English. Besides, the topic of this lesson is led in.)Step 3 Presentation & Practice (20 minutes)1.New wordsShow a map of the world. Tell students that people who live in different zones have different feelings.For example, hotT: Look. In this area, people will feel hot.Enable students to understand the meaning of “hot” by actions.Lead students to act and read the word.( By vivid actions and expression, it’s easier for students to understand and remember these new words. So I will use the same way to teach the other new words such as cool, warm and cold. Large amounts of practice, some little games and my exaggerated demonstration will help students to understand the meaning and correct their pronunciation.)2.Sentence structureShow Chinese flag and American flag.T: The world is so huge. Where is our motherland, China? Let’s find.Is it here? Yes. Compared with other countries, It’s in China. Cold? Hot? Warm? It’s warm in China.Present the sentence structure: It’s in .Lead students to read line by line, two by two.Ask several students to read and praise them timely.Have students to find out the USA in the map. Lead them to say “It’s cool in the USA.” by themselves.3.Set the scene: Mickey will travel to China. He needs to know the weather in different cities.Show the picture of a weather report. And then present today’s weather report for several cities. Have students to use “ It’s in .” to introduce the weather in different cities.( It aims to enable students to practice the sentence structure and prepare for the added activities.)Step 4 Consolidation & Extension (10minutes)1.Do a weather report for Mickey.Tell students that Mickey will travel to Harbin, Beijing, Lhasa and Hong Kong. He needs a weather report of these four cities. So do a weather report for Mickey.T: Who can read the city?S1: Harbin.T: Yes. Stick the city card on the map.( Show a map and ask students who can read the city to stick the card on the map. It adds interests and figures to the study. What’s more, it reflects the trend of the melting of subjects.)2.Chant about Mickey’s travel.Acting like Mickey is traveling. Sing a song about traveling.T: It’s cold in Harbin. Put on a hat. Cold, bye-bye. Let’s go on travel. It’s hot in Hong Kong. Take off a hat. I feel so nice.( I reorganize the chant on the textbook. It’s easier for students to remember and act. The emotion education is infiltrated in this part.) Step 5 Emotion education (2minutes)T: Boys and girls, Mickey is traveling. I miss him very much. So I write a letter for him.Dear Mickey,How are you? It's cold in Harbin. Put on your hat. Cold, bye-bye!China is big. China has many beautiful cities. You can go travelling. Please watch the weather report. Take care of yourself. Enjoy your travelling.Yours,Candy ( It’s nature and interesting to make the contents of this letter as emotion education.)Step 6 Homework1. Copy the words and sentences.2. Write a letter for Mickey. Welcome Mickey to Huaibei.Tell Mickey the weather in Huaibei.Blackboard design:Unit 3 WeatherIt’s inhotwarmcoolcold。
