These are two very encompassing English-learning sites from South Korea. I’m not going to add them to The Best Beginner, Intermediate & Advanced English Language Learner Sites because the initial navigation can be a bit confusing to someone who doesn’t speak Korean, and links to non-English games could be too seductive for learners. The biggest reason, though, for not including them is that a number of the animations, I think, portray the physical appearance of African-Americans (and/or Africans) in a somewhat insulting way. Nevertheless, they both have a huge number of useful resources, and teachers might want to link directly to certain resources on the site that don’t include those animations:
