Learning activities that encourage students to think logically and to discover valid modes of reasoning are receiving increased attention in the elementary mathematics curriculum. Several excellent games through which children learn to ask good questions and to make efficient use of available information have been described in the Arithmetic Teacher (Gessel et al. 1972, Aichele 1972). A concrete setting for a variety of experiences for developing principles of logical reasoning is provided by a set of attribute blocks (Dienes and Golding 1966). In this article a guessing-type game based on these materials is described. While the game in its simplest form can be played and enjoyed by children in the primary grades, it can also be used as a point of departure for worthwhile activities for junior and senior high school students.
