National Parks



Flat Ranger:

Discover the National Parks with Flat Ranger! Students make paper cutout rangers and mail them into National Parks. These Flat Rangers travel with a passport and a letter to different National Parks, asking the Park to mail them information, stamp the passport, and forward the Ranger to another Park. When the passport is complete, the last Park mails it back to the student.

Throughout the year students receive brochures and educational materials from National Parks. Their imagination is fueled as they explore Parks everywhere from Denali to Castillo de San Marcos and learn about important historical events.

The Flat Ranger program includes lesson plans and activities correlated to the Common Core State Standards and the Florida Sunshine State Standards.
