ABSTRACT
This chapter focuses on the theory-driven and media-supported development of trainings that literally go 'one step beyond' conventional approaches by allowing children to move their bodies during the completion of numerical tasks. The authors address not only the mental number line representation but also the place-value structure of the Arabic number system in an embodied training on the digital dance mat. Two training studies were introduced, both using the digital dance mat as input device but addressing two different basic numerical representations. The Mental Number Line Representation of number magnitude - or mental number line - is one of the most broadly investigated basic numerical representations. According to the metaphor of the mental number line, numbers are spatially represented in an ascending order from left to right. The chapter indicates that the embodied training was effective, and also that there were benefits that transcended those of other computer-supported training methods.
