Paul Gunder is the founder of Rocky Mountain Apps, where he builds free calculators, worksheet generators and reference tools used by students, parents and teachers. He is not a classroom teacher. On PrintablePal his job is to make sure every generator produces correct, well-formed problems and answer keys, to match each skill to the grade-level standard it practices, and to explain the method in plain language.
