Columbian Exchange Poster Read the Columbian Exchange handout. 2) Design a poster that illustrates the items exchanged between the New World and the Old World as a result of the Columbian Exchange. Make sure that: A) The items are going in the right direction B) You don’t include things that are mentioned in the handout but weren’t part of the Columbian Exchange. 3) Decide which item exchanged you think was most important. Write the name of the item and a brief explanation of why you think it was the most important on the back of your poster. 4) Grade based on completeness (every Columbian Exchange item mentioned in the reading should be illustrated in some way) and creativity (find a unique way to illustrate the exchange and the items included in the exchange).
