- Pattern block puzzles
- A fun introduction to angle measurement
- Finding and classifying all the symmetries of a pattern-block-tiled regular 3-, 6-, and 12-gon
- Pattern block tilings of the plane, leading to more general explorations (figuring out a notation for pattern block tilings, using that as a springboard towards a search for all the Archimedean tilings, plus some pedagogical brainstorming on how to use triangle and quadrilateral tilings to introduce many ideas in basic geometry)
- Pattern block trains (a problem about rate of change that starts easy and gets very challenging)
- And, if there is time, a brand new pattern block perimeter optimization challenge.

*n*-gons. A full analysis requires basic right triangle trig, but even without that, pattern blocks can help us find perimeter-π for a hexagon, and area-π for a dodecagon.

This will be big fun, so if you're anywhere near San Jose, you should come!
