I'm wondering: what's most the most important thing (anything: concrete or abstract) for teachers here to have with them when teaching an English class.
Me, after 5 years at it, I wouldn't walk into a classroom without a language focus, a properly staged lesson (plan), a bottle of water and, if at all possible, at least 8 hours sleep the night before.
How about other people? What would you not walk into a classroom without?
Cheers
