What are the differences between Our Great Big World and Exploring World Geography?

Notgrass History offers two separate courses that explore the subject of world geography. Both courses include a book of primary sources. They also incorporate literature and offer a variety of activities for students with different learning styles. Both courses have easy-to-follow instructions, so you don’t have to do any lesson planning. Though there are similarities, each course focuses on different things and is geared to a specific audience.

If you have children in early elementary and in high school, you can use both courses at the same time. Exploring World Geography has two units and the beginning and two at the end that don’t directly correspond to units in Our Great Big World. But for most of the year, your kids will at least be learning about the same continent. Tap the button below to see a chart that shows how the units line up.

Exploring World Geography (High School)

Daily lessons guide your student on a fascinating journey across our planet, focusing on how people interact with the physical world around them. If you use the course as written, your student can earn one year of credit in three high school subjects: World Geography, English, and Worldview.


  • The World Geography credit involves reading the lessons and doing the assignments in the Gazetteer (and answering the questions in the optional Student Review if desired). 
  • The English credit involves completing several writing assignments, including one research paper; and reading the assigned literature.
  • The Worldview credit involves examining religious and philosophical perspectives and completing worldview assignments that guide the student in building a Christian worldview.
