1) Gain attention :The teacher comes to the class and that she will distrube a envolope for each group.Envelopes are good materials for drawing attention of students.
2). Informing the learner of the objective: The teacher says what they will o with these envelopes that is, gives the instructions.She makes the groups of 2 people.The students will match the parts of the sentences according to tag question structure.
3)Stimulating recall of prior learning:During the exercise the students recall their past learnings abour tag questions.They think about the rules and form the sentences.
4)Presenting the stimulus:Students give reactions according to stimulus and starts to make questions by group members.
5)Providing learner guidance :The teacher in advanced gived the rules .We don't see that part so much. In the beginning part of the video the teacher talks about the strategies about how to teach tag questions with diffrent games.
6). Eliciting performance :The teacher askes learners the responds.The students starts to giving answer by one by after finishing the exercise.
7)Providing Feedback: After each answer the teacher asks the class whether it is true or not.She doesnt give the answer directly, takes the learners opinions."She ask what do you think."
8)Assessing performance: She asks the class about answers and then verifies the answers.All of the students give the correct answer. The teacher shows her glad by saying "thank you "and very good"
9)Enhancing retention and transfer :The teacher talks about other ways of tag questions with an enjoyable way in my opinion.For example one students form a question other one complete it ,or giving incorrect tags them to correct. So this structure becomes permanent in their memories.

In my opinion the teacher uses different tecniques to use for teaching Tag questions, but we dont see this part namely while she is teaching the rules to the students. The video shows us only the part that after the students has learned the subject.Then she makes the students do enjoyable activity. Because this way is much better than to make them o practices from a book or sheet. This activity make them curious about the exercise (envelope activity ) Than at the end , she also talks about other ways of teaching a grammer. They are creative I think. As the learners like the games an fin them more interesting than common ways the teachers generally use.
