Proof
This interactive workbook begins with a sheet which illustrate properties of odd, even and consecutive numbers. These properties are illustrated numerically and algebraically. The next two sheets deal with properties of the sum, difference and product of these numbers...
This book will interest all those who are concerned with the current state of geometry in school. The concept of proof is a vital part of what mathematics is all about. In this book, the author claims that 'seeing is believing' and using powerful images to provide convincing reasons for the truth of many theorems...

Proofs of the Pythagorean theorem
This task is designed to assess how well students understand geometrical proofs.
The task presents three attempts to prove Pythagoras’ theorem. Students must look carefully at each attempt and determine which is the best ‘proof’. They must explain their reasoning as fully as possible.
This task is...
Like its predecessor, Proofs without Words, this book is a collection of pictures or diagrams that help the reader see why a particular mathematical statement may be true, and how one could begin to go about proving...
Proofs without words are figures or diagrams that help the reader see why a particular mathematical statement is true, and how one might begin to formally prove it true. Many date back to...
