I Step 4 - Defining and practical implications i Time: 8-12 minutes Type: Brainstorming or teacher-focused class discussion With the differences highlighted and discussed, it is now time for the final part. It is always better if the students manage to explain the differences themselves and then the teacher either repeats them or demonstrates more articulate definitions. The more practical examples the teacher or students are able to gather (whole sentences, specific expressions, and the like), the better.
