You may wish to mention that the 4,000-mile-long Amazon is the second longest river in the world. The river begins high in the mountains of Peru, flows eastward across Brazil, and then empties into the Atlantic Ocean. The land in the Amazon River basin makes up the largest rain forest in the world.

The Xinguano people had little contact with the European settlers, who arrived in Brazil in the early 1500s. The Xinguano villages were so remote that Europeans did not reach them until the mid-1700s. Finally, most of the Xinguano died of smallpox, measles, and other diseases introduced into their region by the Europeans.

The Data Hunt activity has students use what they have learned about coordinate graphing to extend their map-reading skills.
