The treasure hunt takes my classroom to the world and features a variety of approaches, conjecture building, and the use of dynamic geometry software. The problem has been written about extensively (Gamow 1947; Nahin 2016; Shilgalis 1998; Shriki 2011). Here is the problem as I have adapted it for my students.
