My tasks in both families were basically taking care of the kids and everything that was involved with them, groceries, driving, some cooking, laundry and cleaning, besides, playing with them at home, taking them to play-dates with their friends, taking them to the library, helping them with some school homework and so on.
I am an English teacher back in my country. I have a degree in teaching English as a second language. So I also have some experience in teaching. I have worked with kids from 5 to 7, 8 to 11 and 13 to 15 year old's in some schools as an English teacher.
