'Where did you learn to swim?' The students write all their partner's answers in the appropriate columns on their worksheet. 'Can you swim?' If their partner replies 'Yes, I can', the student finds out when they were first able to do the ability by asking 'When could you first do this?' Their partner replies and the student asks suitable follow-up questions from the bottom of the worksheet to gain extra information, e.g. In pairs, students take it in turns to ask their partner a 'Can you.?' question from their worksheet, e.g. In this communicative can and could activity, students ask and answer questions about present and past abilities. 'Can he swim?' When the students have finished, they complete sentences at the bottom of the worksheet with information about the students' levels of ability. The students then ask and answer questions about their new partner’s former partner using the third person singular, e.g. When everyone has finished, the students form new A and B pairs and write the name of their new partner’s former partner on the worksheet. If their partner replies 'No, I can't', the student moves on to the next 'Can you.?' question. Their partner responds with one of six phrases on the board that express their level of ability and the student ticks the appropriate 1 to 6 box on the worksheet. When their partner replies 'Yes, I can', the student asks a 'How well can you.?' question. In pairs, students take it in turns to ask their partner 'Can you.?' questions and mark their responses on the worksheet. In this can and can't activity, students practice talking about skills and levels of ability using modal verbs and adverbs of manner.
