The tablet-app ‘Stellenwerte üben’ (Practicing place value) was developed to provide a software for practicing place value concept. There are two goals associated with this project: 1) Developing the app and 2) Investigating how children interpret the given non-symbolic representations and how they use the implemented features. This article presents the underlying theoretical background, a short description of selected features, and a sketch of initial empirical findings on the interpretation and use by primary school children in their second and third school years. First findings suggest that previous experience with concrete physical material overlaps and influences the intended use of the implemented virtual features.
