The Underground Railroad (National Geographic Kids Readers, Level 3)

Learn all about the Underground Railroad, the people who traveled it, and its important role in American history with this National Geographic Level 3 Reader, perfect for independent readers strengthening their academic vocabulary and comprehension.

The Underground Railroad was not a railroad at all, but a secret network of hidden pathways, safe houses, and courageous people who helped thousands escape enslavement to freedom. It connected the “freedom seekers” with the brave “conductors”—such as Harriet Tubman—who risked their own freedom to help guide others to safety.

Young readers will also learn about other incredible helpers (like the Quakers and Frederick Douglass), the various paths to freedom, and important historic events, such as the Civil War and the passing of the 13th Amendment. With compelling illustrations and carefully leveled text, this National Geographic reader introduces a complex topic in an age-appropriate, accessible way.

NGK Level 3 Readers are ideal for fluent readers who are reading on their own with ease, with layered information and varied sentence structure.
