1. Teacher Guide This lesson is designed to teach kids to ask a critical thinking question that you can’t just put into a search box to solve. To do that, we encourage them with smaller questions that search can help them answer. Make sure that you read the notes for each slide: they not only give you teaching tips but also provide answers and hints so you can help the kids if they are having trouble.

3. The origins of the Natchez Trace National Scenic Trail began many centuries ago. Long before Europeans arrived in North America, the trail was used by several Native American tribes as a highway. It once stretched roughly 500 miles, mostly through what is now Mississippi, and also through parts of modern-day Tennessee and Alabama. Today, the trail is maintained by the National Park Service and is open to hikers and horses. The Natchez Trace Parkway is a 444-mile paved highway that parallels the Scenic Trail, allowing modern-day travelers to journey by car or bike between Nashville and Natchez.
