We start with a brief revision of modals of obligation, their meaning, form and phonological aspect so drilling the stress and intonation might be a part of this early stage.

The students work in pairs. Each two pairs are given the same workplace. The pairs are asked to work together and come up with as many rules as possible for the given workplace. This will take about 5 minutes. Next, the pairs with the same workplace are joined together in groups and compare the rules they have come up with for the workplaces. Feedback is provided by the teacher at the end of this stage.

Students are put into groups. Possibly one group of all females, one group of all males and a last group of males and females. They are told that they are going to live together in an apartment flat and have to discuss some rules and regulations for their living arrangement which all must agree on. They are given 10 minutes for this task. Next, the groups are broken and members of each group form different groups with the others where they share their group's ideas and discuss their choices. The teacher walks around the classroom collecting output for the purpose of the feedback stage at the end of the lesson.

The students' erroneous output is put on the board and the students are asked to work in pairs and correct the mistakes. The definitive feedback is provided by the teacher at the end of this stage.
