For the Core Knowledge Curriculum, an extension suggestion is a Tall Tale Map. This a Tall Tale Map for the Pecos Bill, Paul Bunyan, Casey Jones and John Henry.
I included the map worksheet and some modified copies I used. Students labeled and colored, but certain students were given different version depending on their abilities. The answer key is somewhat provided, if you know the tall tales, you know which character belongs to which state and landmarks.
Use this Prezi Presentation too!
