Starting with the simple rule which generates the numbers in pascal's triangle, it is remarkable how many other patterns and properties there are to discover. Any teacher who would like to convey something of the wonder of mathematics to a class at almost any level would find little better than the material contained in this book. It offers potential for investigations and topics at levels from grade school to high school.
