Editor's note: This story accompanies a look at efforts to transform Monument Valley High School. Read the main story here.
Dorothy Bigman, one of Monument Valley High's first graduates, now teaches its students the Navajo language using the tribe's wealth of games and songs.
After one class, in which three girls play a shoe game against three boys, Bigman teaches a class with just two students: Caitlyn Black and Richelle Sloan.
Black reads aloud a story she has written in Navajo about a big, strong deer. She says she wants to master her native language so she'll be more valuable in the health care industry.
