In the previous post I mentioned that I challenge students to do certain things that will not effect their grades, but could earn them some Oswald Dollars. After we completed The Best Die activity, I challenged my students to create two dice that would tie in theory. They could write any positive integers on the six faces of the dice, but it still had to have a sum of 21. Students who were able to do this received 5 Oswald Dollars. Below are the results.
