"I would suggest another target for these well written tomes: professional development of mathematics teachers. At the very least, every middle school and high school mathematics teacher who aspires to enhance their profession should be comfortable with the methods of these volumes. Given the dry tone of some of the stuff I've read by academic mathematicians for HS teachers, these lessons jump right to the heart of the matter, doing so with a bit of humor, simplicity, and elegance."
