School House Rocks was a series of cartoons that taught kids about all kinds of things like language, history, health, and government. They were mostly shown in between cartoons on Saturday morings.
Watch the attached cartoons, take note of the way they use a song to tell the story, notice how very simple the drawings are, and look for anything that makes you laugh as you watch.
These two cartoons are classics that taught kids about the American Revolutionary War.
