math them

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.

When JRMF throws a festival, some activities will invariably be more popular than others. When we introduce enough new activities, some old ones stop stacking up against the rest. While a new activity eclipsing an old one isn't a terrible problem to have, Ladybugs is currently not a fan favorite, and it is one of our more outwardly arithmetical activities. Since having a few arithmetic-forward activities in the bunch make it easier to sell our offerings as mathematical to the skeptical, we'll take a look at it as it stands and consider a reimagining.

Here we'll look at some topological puzzles originally cast in terms of hanging a picture frame.
