Activity 1: Warm-up · 5 minutes
Quick Recall: Past Stories
a) Aims
Ss activate prior knowledge of the past continuous and past simple through a short picture-based question-and-answer routine.
b) Content
T shows a slide with a picture of volunteers sorting donated books when a phone rings. T asks: 'What were the volunteers doing when the phone rang?' and 'What happened at that moment?' Ss answer in pairs, then one pair shares with the class.
c) Expected outcomes
Ss produce two accurate sentences, for example: 'The volunteers were sorting donated books when the phone rang.' Ss notice that the ongoing action uses was/were + V-ing and the interruption uses the past simple. Ss state the topic of the lesson: Looking back, Unit 4.

Step 1: Task delivering
T shows the picture and says: 'Look at the picture. Work in pairs. Tell your partner what the volunteers were doing and what happened next. You have one minute.'
Students
Ss look at the picture and discuss in pairs, using the past continuous for the background action and the past simple for the event.
Teacher
Step 2: Task performance
T monitors and gives quick help with verb forms, especially was/were and irregular past forms.
Students
Ss make sentences such as 'The volunteers were sorting books when the phone rang.' Some pairs may say 'The phone rang while the volunteers were sorting books.'
Teacher
Step 3: Report and discussion
T invites two pairs to share their sentences and writes the best examples on the board.
Students
Two pairs read their sentences aloud. Other Ss check whether the verb tenses are correct.
Teacher
Step 4: Conclusion and assessment
T confirms that the sentences show an action in progress (past continuous) and a completed event (past simple). T announces the lesson aim: to review the unit's grammar, vocabulary and stress.
Students
Ss copy the aim of the lesson into their notebooks.
