Dr. Montessori writes about the "three legged stool" of arithmetic, algebra, and geometry. The focus of adolescent mathematics is mainly in algebra, but geometry and arithmetic should not be ignored and will be discussed in this volume and those following. In practice, the three branches of mathematics are closely related and should be used together.

The topics in this book are a summary of my own lessons and are organized to demonstrate what needs to be presented to adolescents for the understanding of the algebra portion of a mathematics program. This is not a textbook. It is simply a set of lessons based on Montessori elementary materials which has been uniquely adapted and expanded for the adolescent.
