I'm a retired math teacher (everything from algebra through AP calculus and college classes, to boot). One of the most enjoyed days was the one in which I had one of our school secretaries as a guest speaker in a high school geometry class with about half boys and half girls. Mrs. Kneidinger became a rock star to those kids. She brought in a dozen or so quilts and some smaller quilted projects (her lunch hour diversion) and talked about the various quilt blocks and how the squares, rectangles, and triangles had to be cut and sewn precisely to fit together properly. They were full of oohs and ahs and peppered her with questions. For months after that they would pop in to the office to ask if they could see what she was working on next. This caused such a stir that one of the home ec teachers decided to put in a unit on making quillows. And you can bet that I used quilt block patterns for demonstrations and quiz questions. The kids really took to it.
