The activity is practical because it is very easy for the teacher to set up, it does not require a lot of preparation or materials. The activity is adaptable as it can be used to practise a variety of different language points with different ages of student, from children to adults, for more advanced learners the questions and conversations can be longer and lower level students can use the same activity to practise more basic questions and answers. It allows students some freedom to use a wider range of language and the activity allows students to construct their own sentences as well as personalise the topic. The activity manages to engage all students in speaking in pairs at the same time, giving the teacher an opportunity to monitor and assess individual students' ability to use the target language. This activity is also student-centred encouraging student-student interaction in a meaningful task. Teachers with large class sizes and limited space may have to think about how to carry out this activity without too much disruption and noise, asking students to carry out the activity seated and only moving once the teacher gives the instruction to do so may be one way to achieve this.
