4th Edition (2019)
For the 2019 printing, we made minor corrections and updates to the curriculum, primarily in Lesson 150. We made some significant changes to the Exploring America Student Review Book to address concerns some parents had expressed about the difficulty level. We also updated the Answer Key to match.
All of the 2019 components are compatible with the 2014 components except the student review material. If you have a 2014 Student Review Book or Quiz and Exam Book, you need the 2014 Answer Key. If you have a 2019 Student Review Book or Quiz and Exam Book, you need the 2019 Answer Key. All of our answer keys are available as free downloads.
Look for the red box that says "2019 Edition" on the cover of your books to distinguish between the 2014 and 2019 editions.
3rd Edition (2014)
Released in 2014, this edition covers essentially the same material as the second edition with some changes to Unit 30 to cover events up to the date of publication. It has a completely new page layout with full-color photographs and illustrations and a hardcover binding. We modified the literature list, dropping Little Women and Christy and adding Miracle in the Hills. The new Student Review Pack, which replaces the former Quiz & Exam Pack, also includes literary analysis.
2nd Edition (2007)
For the 2007 edition, we reformatted the entire curriculum with some modifications to the table of contents and published it in a paperback binding. We created our own one-volume book of speeches, documents, poetry, and short stories called American Voices. The Quiz & Exam Pack for the second edition is available for purchase as a digital download.

2007 Guide for Parents and Teachers
This lesson is a special addition to the 2007 edition of Exploring America. There are no questions in the Quiz and Exam Book, no activities related to it, and no quiz that includes it. It is simply a way to extend the curriculum package to include events in 2008 and 2009.
1st Edition (2002)
The first edition of Exploring America was published in 2002. It had a plastic coil binding and used three supplemental document books (World's Great Speeches, Documentary History of the United States, and 101 Great American Poems). The Quiz & Exam Book for the first edition is available for purchase as a digital download.
Corrections (2019 Edition)
Bible Exam on Units 1-5
The questions on the first Bible Exam should be numbered from 1-25 instead of from 5-29. The answers in the answer key are correctly numbered.
Unit 13, Lesson 61
In the description of the Battle of Shiloh at the bottom left of page 340, we say that General Sherman led Union reinforcements to the battle. Sherman was already at the battle on April 6. General Don Carlos Buell led the reinforcements.
Unit 18, Lesson 88
On page 503, the text refers incorrectly to Hull House in Chicago as a "tenement house." The correct term is "settlement house."
Corrections (2014 Edition)
Unit 6 Quiz Answers
The page numbers for the first three answers in the Answer Key are incorrect. Here are the corrected answers and page numbers: 1. N (146-148); 2. H (142); 3. O (149-150)
Bible Assignment for Lesson 36
The Bible Assignment at the end of Lesson 36 was vague. Here is an updated assignment: The Bible study lesson this week looks at religious activity in America in the first half of the 1800s. One feature of this activity was the rise of several movements or groups that claimed to have a deeper insight into truth than what traditional Christianity offered. Read Colossians 2:16-23. List three things outside of Christ that people mistake for true spiritual fulfillment.
History Exam for Units 16-20
The answers for questions #6 and #7 should be switched. #6 should be Populism and #7 should be Progressivism.
Unit 24, Lesson 120
In the caption on page 708, we incorrectly identified the author of the Pledge of Allegiance as Edward Bellamy. The correct name is Francis Bellamy. Francis and Edward happened to be cousins.
