Uncle Norm’s “hush hush” work is getting kind of slow, so he needs to pick up business at his Stuff ‘n Such Shop. How can he do it? With a banner sign! He meets with a math teacher who shows him how special folding techniques, combined with cutting cool shapes can make for a really neat linking banner.

The Gist: This episode is about congruent shapes, patterning, symmetry, and simple transformational geometry. Using a simple doll pattern and specific paper folds, (also knownas a “generator”), it is possible to generate many concrete representations of slides, flips and turns.
