Activity 1: Warm-up · 5 minutes
Lead-in: What Makes a District Livable?
a) Aims
Ss activate prior knowledge about city life and preview the key vocabulary of the lesson.
b) Content
T shows the question on the board: 'What makes a district livable?' Ss work in pairs and list three ideas. T then checks the meaning of six key words: livable (đáng sống), infrastructure (cơ sở hạ tầng), sensor (cảm biến), privacy (sự riêng tư), pedestrian (người đi bộ) and efficient (hiệu quả). Ss match each word with a short definition or example.
c) Expected outcomes
- Each pair lists at least three ideas, for example: shaded paths, reliable buses, clear public information.
- Ss correctly match the six key words with their meanings and example phrases, for example: 'a traffic sensor' = a device that records traffic data; 'pedestrian routes' = paths for people walking.
