A description of the author's journey as she revised a geometry unit for prealgebra and general mathematics classes to reflect her changing beliefs and practices about learning and teaching mathematics. Student input on a unit of geometric transformations led to a transformation in the author's beliefs about teaching.

Students can acquire a greater understanding of triangle congruence through this hands-on-activity: constructing a quilt pattern and writing its description for a catalogue. Ultimately, student writers become conversant about the technical geometric jargon.

A variety of patterns and mathematical tools used to explore Moser's circle problem. Moser's circle problem is rich with connections to Pascal's Triangle, combinations, Euler's Formula, and Finite Differences and many geometric patterns.
