A little embarrassed to actually publish my post today. We built our own decks…..umm a while back…..when we were working on the ark problem. We had pinned them to the bulletin board with the intent of checking if they were indeed balanced. I needed to make room for some other work on the board today and as I removed our “decks,” realized we never did get around to finishing. Shame on me! But so glad to have an opportunity to revisit such a great problem.
