Unit 7 What’s the highest mountain in the world? Section B（1a - 1d） Teaching Objectives By the end of the lesson, students will be able to: Compare two animals (elephant and panda) using superlative and comparative language, mastering structures like “many times more/less than” (1a). Extract numerical information about pandas from listening materials, improving number recognition in context (1b). Complete sentences with key details about pandas, focusing on birth weight, length, appearance, and lifespan (1c). Describe pandas to classmates, using target language and listening - derived facts (1d). Teaching Key Points & Difficulties Key Points Using comparative structures (e.g., “weighs many times more than”) to compare animals. Accurately catching and using numerical data in descriptions. Difficulties Formulating complex comparative sentences for animal traits. Distinguishing similar numbers (e.g., 0.1 vs. 0.2) in listening. Teaching Methods Animal Comparison Practice Listening Comprehension (Number & Fact Extraction) Oral Description & Sharing Teaching Aids Textbook, blackboard, multimedia, audio player Teaching Procedure I. Warm - up & Animal Talk (7 mins) Daily Question Ask students: “Do you like elephants or pandas? What’s one fact you know about them? ” Let 3 - 4 students share, e.g., “Pandas eat bamboo. Elephants are very big.” Lead - in to 1a Say: “Today we’ll compare elephants and pandas using superlative/comparative language. Let’s start with 1a!” II. 1a Activity – Animal Comparison (10 mins) Instruction Show 1a animal facts (elephant vs. panda height, weight, food). Tell students: “Use the example sentence to make your own comparisons. Try ‘taller/shorter’, ‘eat more/less’.” Example: “This elephant is 200 cm taller than this panda (350 - 150 = 200).” Student Activity Students write 3 - 4 sentences (e.g., “The elephant eats 140 kilos more food a day than the panda.”). Pair up to share. Walk around to praise: “Good use of ‘many times more’ – the elephant eats 15 times more food! (150 vs. 10).” III. 1b & 1c Activities – Listening for Panda Facts (18 mins) 1b Pre - listening Show 1b numbers (100, 16, etc.) and tell students: “These numbers describe panda facts. Predict which number matches (birth weight, length, etc.).” 1b While - listening Play 1b audio. Students check numbers they hear (e.g., 0.1, 100). 1c Pre - listening Explain 1c: “Fill in blanks about panda birth facts. Listen for numbers and descriptions.” 1c While - listening Play 1c audio. Students fill in: 0.1; 0.2 kilos (birth weight) 15 cm long (birth length) pink; no teeth (birth appearance) 20; 30 years (lifespan) Play twice. Walk around to confirm: “‘0.1 to 0.2 kilos’ – that’s very small! ” IV. 1d Activity – Panda Description (7 mins) Instruction Explain 1d: “Take turns telling classmates about pandas using 1b/1c facts. Use sentences like ‘At birth, a panda is very small...’.” Student Activity Pairs practice: A: “A baby panda is only 0.1 to 0.2 kilos at birth!” B: “And it’s pink with no teeth!” Invite 2 - 3 pairs to share. Praise accurate details: “Good job mentioning the lifespan – up to 30 years!” V. Summary & Homework (5 mins) Summary Recap key points: Comparative language for animals (elephant vs. panda). Panda facts: birth weight, length, appearance, lifespan. Write on the board: Panda Facts: 0.1 - 0.2 kg at birth, 15 cm long, pink, no teeth, lives 20 - 30 years. Homework (1) Write 3 more panda comparison sentences (e.g., “An adult panda is much heavier than a baby panda.”). (2) Draw a baby panda and label its birth facts (weight, length, color).
