This document presents five activities which represent a part of the Comprehensive School Mathematics Program (CSMP) curriculum. The package is primarily designed to: (1) introduce instructors to one or more of the three non-verbal languages used in the CSMP elementary curriculum in such a way that teachers would want to pursue the possibility of adopting the curriculum; and (2) to provide some mathematically rich activities for immediate classroom use. This package introduces a classification game. The five activities are written in standard CSMP format of teacher-student dialogue. It is hoped the material will provide teachers and their pupils with a setting that allows for joyful development of logical and strategic thinking. (MP)
