This paper justifies the teaching of cartography in secondary schools and expands graphic knowledge by providing a formal graphic language simulation lesson. The cartographer's task, decisions, and methodologies are approximated by the use of this role playing scenario. Students assume the roles of map authors who are contracted to draw up a set of maps depicting the fire damage risk for the properties in a one block area of an industrial city. Using the materials provided--including photographs, census data, hydrant and fire alarm locations, traffic flow charts, and building locations--students familiarize themselves with the data and set about attacking the problem. The end products of their work are maps which are evaluated by the class to see who will be awarded a further contract. The final section examines the simulation for its value as a decision-making exercise, its conveyance of the cartographic system, and as a communication exercise in self-expression. (Author/DE)
