Warm - up & Geography Review (7 mins) Daily Question Ask students: “From 1c, what’s one superlative fact you remember? (e.g., Qomolangma is the highest mountain).” Let 3 - 4 students share, e.g., “The Nile is the longest river in the world.” Lead - in to 2a Say: “Today we’ll learn more about China and the US – their rivers, age, and size. Let’s listen to facts and practice conversations.” II. 2a & 2b Activities – Listening for Numbers & Facts (18 mins) 2a Pre - listening Show 2a numbers (6,300; 5,000; 5,464; 300) and tell students: “These numbers describe China/US facts. Predict which number matches each fact (river length, country age).” 2a While - listening Play 2a audio. Tell students: “Listen and number the facts [1–3] in order. Focus on numbers and what they describe.” Play the audio twice. Pause to let students write. 2b Pre - listening Explain 2b: “Fill in 2a blanks with the correct numbers. Check if your 2a order matches.” 2b While - listening Play 2a audio again. Students fill in numbers: Yangtze: 6,300 km; Yellow River: 5,464 km China: 5,000+ years old; US: 300 years old Check answers: Fact 1: Yangtze (6,300), Yellow River (5,464) Fact 2: China (5,000), US (300) Fact 3: China (biggest in Asia) III. 2c Activity – Conversation Practice (10 mins) Instruction Show 2c sample dialogue: “A: Did you know China is one of the oldest countries? B: Yes... older than my country.” Tell students: “Use 2a facts to make conversations. Compare China and the US (age, size, rivers).” Student Activity Pairs practice, e.g.: A: Did you know the Yangtze River is 6,300 km long? B: Yes! It’s longer than the Yellow River (5,464 km). Walk around to encourage superlatives: “China is the oldest country in Asia – use ‘oldest’.” IV. 2d Activity – Great Wall Role - play (10 mins) Instruction Show 2d conversation (Guide & Tourists). Tell students: “Role - play this dialogue. Pay attention to questions about length, reasons, and parts of the Great Wall.” Explain new phrases: “ancient emperors”, “man - made objects”. Student Activity Groups of 4 (1 Guide, 3 Tourists) practice. Walk around to correct pronunciation, e.g., “Badaling – ba - da - ling”. Invite 1 group to perform. Praise: “Good use of ‘longest wall in the world’ – correct superlative!”. V. Summary & Homework (5 mins) Summary Recap key points: Numerical facts: China/US age, river lengths. Conversations with superlatives/comparatives. Great Wall role - play skills. Write on the board: Key Structures: -... is [number] kilometers long. -... is one of the oldest countries. Homework (1) Write 3 sentences comparing China and another country (e.g., “China is older than Australia.”). (2) Research one more fact about the Great Wall and share in the next class.
