Review of roots to research by Judith D. Sally and Paul J. Sally, Jr.

“Roots to Research” traces the development and presentation of five mathematical problems from the early grades of elementary school to, in some cases, upper graduate level mathematics. In contrast to most mathematical texts, the development is vertical; each of the problems is first presented at a fairly low level, and then developed using more powerful mathematical tools. As such the authors introduce a variety of mathematical fields by showing how these specific problems can be addressed using tools from those fields.
