Work-in-progress—Visualization of Area Units with Augmented Reality

Area measurement has a high priority in mathematics school education. Nevertheless, many students have problems understanding the concept of area measurement. An AR tool for visualizing square units on objects in the real world is developed to enable teachers to support understanding already in primary school. This work-in-progress paper presents the initial test version and discusses the first teaching experiment results. The students’ feedback and use of the app showed possible adaptations of the AR tool, e.g., that the idea of dynamic geometry could be incorporated in the future.
