Indicates in-class and at-home math projects for sixth graders. Activities focus on map-making and exploration of maps. (RH)

Thoughts of diverse individuals concerning mathematics are reprinted. Quotations are presented in four categories: philosophical, aesthetic and creative, emotional, and scientific. The author opines that the classroom use of such quotations can provoke thought about the nature of mathematics. (SD)

The mathematics of cryptology is discussed. Methods for deciphering a code and for ciphering schemes are detailed. (DT)

The material in this booklet is concerned with a discussion and examination of geometric puzzles and the ideas which result from their study. The general idea of graphs is introduced as a tool which can be used to solve geometric puzzles. The fact that working with puzzles can lead to unexpected mathematical discoveries is stressed. Such topics as…
