Sona are geometric sand drawings that are used in conjunction with traditional storytelling by the Chokwe people of Angola Africa. In the tradition, a storyteller smooths and pokes a grid of dots into the sand. As they tell their story, they draw lines weaving between the dots, following certain rules and matching the rhythm of their story. Whenever a line hits a boundary, it reflects back into the grid, and by the end of the story, every dot is surrounded and all of the lines have reconnected to themselves creating loops (see the linked poster for an example). Join us for an interactive activity exploring fascinating the mathematics behind these drawings!
