Opening the exchange

Ss activate prior knowledge about international cooperation and predict the purpose of a short invitation.
b) Content
T shows a picture of an exhibition about international cooperation and asks: 'What do you see? Who do you think organises events like this?' T then asks Ss to guess what the invitation in the lesson is about, using the word 'invite'.
c) Expected outcomes
Ss give 2–3 predictions in English, for example: 'It is an invitation to an exhibition.' 'Someone is asking a friend to come.' Ss also name one way to accept an invitation politely, for example 'I'd be delighted to.'

Step 1: Task delivering
T shows the picture and asks: 'What is happening in this picture? What is an exhibition about international cooperation?' T gives the instruction: 'Look at the picture, then predict what the conversation is about.'

Ss look at the picture and listen to the instruction. They think for 30 seconds before speaking.
Teacher
Step 2: Task performance
T walks around and prompts with questions: 'Who is inviting whom?' 'How can you say yes politely?'
Students
Ss discuss in pairs and note their predictions in their notebook. Expected answers: 'It is about an exhibition.' 'A student invites a friend.' 'I'd be delighted to.'
Teacher
Step 3: Report and discussion
T invites 2–3 pairs to share predictions and writes key words on the board.
Students
Representative pairs report their predictions to the class, for example: 'We think A invites B to an exhibition on Friday.'
Teacher
Step 4: Conclusion and assessment
T confirms the topic: 'Today we will read a short invitation about international cooperation.' T links the predictions to the lesson and introduces the unit title, Viet Nam and international organisations.
