This outline is for a pre-algebra course designed to prepare students for algebra or to satisfy a one-year mathematics requirement. A key purpose is to present a practical mathematical experience. A detailed outline is given with a suggested time allotment for each chapter. A discussion of each topic follows with teaching suggestions and examples. The chapters are partitioned as basic units and supplementary units. Topics in the basic units include: integers; rational numbers; graphing; measurement of geometric figures; ratio, proportion, and percent; probability and statistics; and consumer and job-related mathematics. Supplementary units include: informal geometry; recreational mathematics; flow charts and calculators; volumes of geometric solids; and mathematical reasoning. (MP)
