EXAMPLE
1) The teacher might set the class the task of devising some ‘class rules’ with regards to such things like classroom etiquette, discipline, duties, homework etc.
2) Individuals draft a list of a maximum of the rules.
3) They then compare the in pairs, and draft a new list of the rules and they are both agreed on.
4) They then join with another group and have to agree again, and so on, until the whole class is involved in one discussion.
