This lesson explores the Silk Road from Chang'an, China, to Rome, sometime during the second century C.E. Students learn to think as traders in six cities along the Silk Road, bartering with traders from neighboring cities. As the silk moves west toward Rome and gold moves east toward Chang'an, students will see changes in the values of the goods they trade. After an introductory reading about the Silk Road, the students will use economic reasoning to calculate the prices for goods along the Silk Road. They will then learn if a trade is a good deal or a bad deal. Finally, the students decide if it is beneficial to take other routes to China.
