I know when I taught in Sunday school I would have the kids go around the room and tell me one exciting thing that happened during their week. I would also start off with a game that required the kids to interact with each other and for the most part it worked every time
that would work with my extrovert students because they always volunteer. my introverts would just stay in the background. i try to remember back when i was their age (12-14 yr old) to see how i can get them involved. but it doesn't help cuz i was the weirdo kid! haha i would talk in class only if the teacher asked me a question directly, but i remember hating that because then everybody was looking at me.
i know i can do this. God gives me the creativity.
