One of the concerns we sometimes discuss in the Substitute Teacher’s Course is “How do you quiet an entire class?”
Yelling is not an option.
Age is certainly a factor–some of the more common techniques involve ringing a bell, flicking the lights on and off, using hand gestures. When I’m in a strange school or class, I try raising my hand first–it seems to be somewhat universal.
Today I read one to use with the littles that I just might have to try because it’s fun! The instruction to “pop in a marshmallow” tells everyone to pretend they are putting a big marshmallow in their mouth. (Don’t hand out real marshmallows!) This means lips are closed and cheeks are puffed out. It’s pretty hard to talk with a big marshmallow in your mouth! I’m thinking it might also work with kids in the back seat of the car.
