It would be helpful to have a large map of the U.S. for the history portion. Ask children if they have ever seen a train or railroad tracks in real life, television, or the movies.
Children can work directly with the computer.
They can click on the various subjects and see text and drawings. Teachers can make transparencies to go over items with class as a whole. The sketches can be colored and displayed in various parts of the classroom. For first grade and special education groups, Thomas the Tank Engine videos may be appropriate. For second and third grades, the game Express-the Railroad Card Game teaches railroad items and terms in a fun way.
