Participants will develop a deeper understanding of the definition of parabolas, ellipses, and hyperbolas by paper folding; discover that what looks like each conic section is really the "envelope" of tangent lines; find where the loci of points actually are; mimic the same actions on the TI-NSpire; and compare and contrast the ellipse with the hyperbola.
