America’s Heritage: An Adventure in Liberty is an award-winning K-12 supplemental lesson plan resource utilized by over 140,000 teachers in all 50 states.

Curriculum Overview

America’s Heritage: An Adventure in Liberty is a performance-tested teacher lesson plan resource developed by AHEF to strengthen K-12 education in the founding documents, institutions, history, and principles of the United States of America. The resource aims to provide teachers and students with opportunities to explore and understand the meaning and significance of events, causes, and effects–the whys–relating to and influencing early American history and its founding governing principles. All lessons emphasize one or more AHEF themes of Freedom, Unity, Progress, and Responsibility (FUPR™) and provide students with opportunities to assess and examine their identities as Americans.

What Our Free Lesson Plans Include

Written by and for teachers of social studies, U.S. history, U.S. government, political science, civics, geography, economics, and related subjects, this supplemental resource consists of ready-to-use, modifiable lessons and learning activities in three volumes–elementary, middle, and high school level. Elementary (K-5) lessons correlate with the national Core Knowledge Skills. Middle school (6-8) and high school (9-12) lessons correlate with the standards and objectives of the National Council for Social Studies (NCSS).

As a supplemental program and resource, Adventure in Liberty may be used within any curriculum, school, or district to help teachers and homeschooling parents improve student learning, performance, and enrichment in these subjects. It requires no teacher training.

AHEF Engages Students in Learning American History

Adventure in Liberty has been tested and shown to improve student performance in history and social studies.

In 2002, the resource was evaluated for student performance results in a study of 8th-grade social studies students based on the Texas Assessment of Academic Skills (TAAS), a test measuring American History objectives taught by schools nationwide. The study showed that students whose teachers use Adventure in Liberty increased performance in Social Studies Historical Concepts and Information. These findings demonstrate the value of this resource in improving student performance in related social studies subjects. (See 1st Resource Evaluation Study.)

In 2003, a second study was conducted comparing student performance on the TAAS between students whose teachers used Adventure in Liberty and those whose teachers did not use the resource. Among students whose teachers used the resource, Hispanic students, in particular, improved in performance on the TAAS in U.S. History Economic and Social Influences. These findings demonstrate the value of the lesson plan to reduce the achievement gap between Hispanics and other ethnic groups. Hispanics are the fastest-growing ethnic group in the United States. (See 2nd Resource Evaluation Study.)

K-12 teachers, administrators, homeschoolers, and AHEF partners offer high praises and endorsements for Adventure in Liberty. See AHEF Endorsements (PDF). See also What Teachers & Homeschoolers Say About AHEF Resources (PDF).

AHEF, in partnership with other community service organizations, including the National Society of the Sons of the American Revolution (SAR), has distributed over 180,000 copies of Adventure in Liberty to teachers and homeschoolers in public, private, and home schools nationwide as well as to individuals, churches, civic groups, and other organizations. AHEF and teachers have reached over three million students in the nation and world with Adventure in Liberty! A national leader! Resource use and distribution continue to increase. Yet this number is only about 6% of all students in the United States studying American history. AHEF is currently working to expand its programs and develop resources to include college-level students.
