This is the perfect power point presentation to teach the Columbian Exchange. The explanation for all that is included in the Columbian Exchange is illustrated and amplified by the slides and the many links leading to online animations, maps, and resources. The worksheet mirrors several of the slides and the answer key is included in the presentation. I find the worksheet channels some of the discussion and invests the students in the presentation as they wait to compare their answers . There are several slides included that offer additional resources and project ideas.
