In grade school I don't think it was covered at all. American history might have been an elective subject in High School but I can't recall.
Our biggest exposure to US history is through the media. Growing up I was exposed to things like
School House Rock,
The Wonderful Stories of Professor Kitzel and other form of Disney history. In fact, living on the border of a pop-culture giant like the US we were subjected to more of their history and culture than our own.
