If you haven't seen the "If You" series for beginning readers it is a great set of books. We own If you...
Traveled West in a Covered Wagon, Lived at the time of the Civil War, Lived with the Sioux Indians, Pioneer on the Prairie, Lived When There Was Slavery in America.
They are written to entertain young readers with American History. They do this by asking questions that would help children really "feel" that moment in history.
For example the "Traveled West in a Covered Wagon" asks:
What kinds of people traveled west?
What would your family bring in their covered wagon?
How would you cross rivers when there were no bridges?
Where would you sleep?
How would you go to school during the trip?
These are great interactive and thought provoking books about our past.
