The website above is from designed for 5th graders in a school in North Carolina. The first thing that strikes me is that 5th graders are young in age (elementary school level I think!). Therefore as expected the topic is slightly watered down for them. It teaches immigration using puzzles and activities and encourages external research of the topic. There however does not seem to be any sort or "over-Americanisation" of the topic. They do not seem to teach it differently in America. The website in particular focuses on Ellis Island.
