Welcome to Week 15 of the Wednesday Morning Math Challenge. You can find solutions to the Week 14 puzzles here, along with — more importantly — discussions of some ways to approach them. Remember that the real goal here is to think creatively.
This week we’re going to have a Christmas puzzle. Santa is at the North Pole and needs to visit all the good children. He needs to do it quickly though, so he can only visit each house once, and then return back to the North Pole immediately. Can you find a path from the north pole that visits each house exactly once, and then returns back to the North Pole at the end?
