I teach English for an international shoe company that has factories in several countries. I thought as a nice gesture, I would add a weekly English lesson (without mandatory homework). Since it's only once a week, it needs to be easy and effective.
I was thinking:
Part 1: 2 idioms related to a theme with similar grammar.
Part 2: 5 grammar exercises related to each idiom
Let me know your thoughts please.
Thanks in advance.
