Extended speaking is an opportunity to practise all the skills needed for communication.
Example
The learners have been reading about xenophobia in different countries and they now share their opinions on causes in an open class discussion.
In the classroom
Extended speaking activities can include speaking games such as ‘Just a minute', presentations and discussions led by learners, interviews, and informal conversation. Jigsaw reading or listening tasks may also give an opportunity for extended speaking.
