The maps were created by expert sailors using sticks and cowrie shells to record the relationship between land and sea. The two types of Marshall Island stick charts are what I found interesting. The map, a rebbelib, covers all or a significant portion of the Marshall Islands. The other chart of a type known as a Mattang was designed to serve as a training ground for those chosen to serve as navigators. It shows a broad overview of swell movements around small islands.   Embodied mathematics is significant in the history of math as ancients found some mathematical concepts through it. The reading shows that they absorbed knowledge from the environment. Specifically, the people of Marshal Island used both their sense of direction and their observation of wave motion to determine the pattern of the swells.   Interactions with our environment lead to learning, and we learn through bodily movements. Students use gestures to express what they are thinking, and embodied activities c...
