In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent villages along the river valleys. As they learn about different ways of life, learners also explore the benefits of trading. Learners act out a trading scenario, in which they make and trade goods including wristbands and popcorn snacks. This activity is featured on pp.23-24 of the "One With the Earth: Native Americans and the Natural World" multidisciplinary unit of study for kindergarten through third grade.
