math them

Gord Hamilton's Kickstarter for The Infinite Pickle is very close to meeting its goal, so I thought today we'd look at a small corner of Boring Conversations , an activity from this collection that was presented this week at the Math Incubator workshop.

My colleague, Daniel Kline, was looking at chain linking manipulative and wondering what activities could make use of them. While he's working on an activity based on symmetries, I thought I would write one up based on de Bruijn sequences.
