Here's an example I got from my textbook, also a picture if that works better for you! (:
Old world: Rice in the Far East, wheat and barley in the Middle and Near East, millet and sorghum in Africa, maize, beans and squash in Central and Andean America, among others, are some examples from the old world.
New world: Artichokes, avocados, beans (kidney and lima), black walnuts, blueberries, cacao (cocoa/chocolate), cashews, cassava, chestnuts, corn (maize), crab apples, cranberries, gourds, hickory nuts, onions, papayas, peanuts, pecans, peppers (bell peppers, chili peppers), pineapples, among others, are some examples from the old world.
Hope this helps! (:
