Diné are also quite active on the scholastic chess scene. Their chess teams were among the very best in the 1970s. Chess just requires a board and some pieces. Math, some paper and a pencil. Any hogan on the Rez, with or without running water or electricity, can support chess or math. No need for English either. (And it just struck me that both use algebraic notation.)
