Activity 1: Warm-up · 5 minutes
Warm-up: Disposable or reusable?
a) Aims
Ss activate their ideas about waste at school events and recognise the link between a problem and a green solution.
b) Content
T shows the sentence 'Our class party used 200 plastic cups. Is there a better way?' Ss discuss in pairs: What is wasteful about disposable items at school events? What reusable or green alternative could we use?
c) Expected outcomes
Each pair writes down two problems caused by disposable items (for example: 'a lot of plastic waste', 'cups thrown away after one use') and two green solutions (for example: 'borrow reusable cups', 'sort waste into bins').
d) Organisation

Teacher
Step 1: Task delivering
T shows the slide and asks: 'What is the problem with using 200 disposable cups? What could we do instead?' T introduces the word disposable (dùng một lần).
Students
Ss listen and look at the slide, then repeat the new word after T.
Teacher
Step 2: Task performance
T asks pairs to think for one minute, then discuss and note their ideas. T walks around and checks the vocabulary used.
Students
Pairs discuss. Expected ideas: 'Disposable cups create a lot of waste.' 'We can borrow reusable cups and wash them after the event.'
Teacher
Step 3: Report and discussion
T invites two pairs to share their problems and solutions. T writes the ideas on the board.
Students
Two pairs report. Other pairs add or agree with ideas, for example: 'We also need a bin for returned cups.'
Teacher
Step 4: Conclusion and assessment
T praises relevant ideas and states the lesson aim: 'Today we will read and write a problem-solving report that proposes green solutions.'
Students
Ss write the lesson title in their notebooks and predict what a problem-solving report contains.
