"Reading multicultural literature can help children gain a better understanding of people from other countries and ethnic backgrounds. These stories may describe how people live in different parts of the world, or they may portraying how children from different cultural backgrounds live together in the same country. They can be fiction, nonfiction, folk tales, fairy tales, legends, or poetry, but above all they must be accurate and portray characters in positive, non-stereotypical ways."
