from 3D to 2D and back

Summary:

Craft: Peel oranges and potatoes. Learn how to build 3D objects by folding up 2D patterns. To build the 2D model of the object, cover it with masking tape, then cut the tape off and lay it flat.

Math: Understand how to manifest curvature in objects, combining geodesic cuvautre and angle defect together. Learn how map makers make maps, and the various tradeoffs required.
