I found this Website to help my class understand the Silk Road https://www.chinahighlights.com/silkroad/new-silk-road.htm
It is a great resource and easy for my middle school students to follow. I teach 7th grade World History, and It explains all about what the Silk Road was and how it is used today. It has several different links explaining all different aspects from trade to tourism.
We will be using it so that the students can see the significance of the Silk Road and the impact that it had on the rest of the world.
