I received a post from Dan Meyer blog, and sent it to you last week. Since then, Jacob W from class sent a nice solution, and I've followed what others have commented.
The reason for Dan's post was to comment on the need to "do math", and be as intentional about our last or favorite math problem as we might be about our favorite or last book read. Luckily, I stumbled on comments from Keith Devlin and a new site for cool problems, Brilliant.
