1. The teacher will ring a bell or motion for a student to ring a bell which then prompts all the students to look at the teacher hands on heads. -Prep
2. The teacher says "Okie Dokie" and the students parrot it back to her. -Prep
3. The teacher says "1,2,3 Eyes on Me" and all the students turn and look at her. -1/2
4. The teacher says "Snap Crackle" and together teacher and students say "Pop" -3/4
5. The best on that I have seen was during a Prep Library lesson (their first). The teacher taught them the song 'Did you feed my cow' which involves the singing of a question from the teacher and then the students singing the answer. At the start of the lesson he taught them this song before sending them off to complete an activity, when he wanted the students attention he would sing "Did you feed my cow" and the students would all sing back "Yes Man" effectively bringing their attention back to him.
I wonder what method I will use when I am a teacher, maybe the method that you use is effected by what grade you are teaching. How would grade 6's respond to having to sing "okie dokie"? I doubt that they would respond well to the 'Did you feed my cow song" mainly becuase they might feel that they should be above that and act accordingly and they are not as happy and eager to please as Preps are.
