Well, it is supposed to be Christopher Columbus sharing his point of view from 500 years ago. I think that's an important point that gets lost when people simply quote the one line from the video.

I think this is the discussion point to have: "Someone from 500 years ago might have thought this way, but what do you think? How is the world different now? What would it have been like to be alive back then? Why do you think they thought this way?"

The video says grades 3-6. I think my "3rd grader" would probably find is boring because it is mostly dialog back-and-forth, but maybe in a few years.
