We report research on meanings of scale generated by pairs of 14 year-old students engaged in joint map-construction. Characteristics of the learning environment, such as the communicational orchestration, the use of experientially familiar objects in space as starting points for creating figural representations and the interrelated representational registers of tangible objects, graphical and formal symbolic representations were important. The task to create maps allowing for dynamic scale change encouraged students to focus on the proportional aspects of scale in all three phases of the task, while they progressed from a componential to a holistic view of the map.
