Cartoons provide the visual representation of a good sentence, a juxtaposition, a pun, a witty interpretation. A cartoon is a good use of Multiple Intelligences. Using a cartoon format so that the scholars can extrapolate the meaning of a poem, a short story, a play, a novel is just one more way we can help our scholars express themselves. A cartoon can augment the essay or other method we ask our scholars use to demonstrate their learning.
