Ooops!  Change of plan...I nixed Black Elk's Vision and substituted another biography to use with third grade and some of our bilingual fourth grade classes...The Hallelujah Flight by Phil Bildner, illustrated by John Holyfield, and I am sooo glad I did!  Great, great book.  The kids loved it, got into the story, enjoyed the illustrations and even joined me in reciting the repetitive phrases!
