In this paper we present the idea of Exer-learning games - integrating the element of exercise into serious games. The combination of motion, learning and playing is assumed to facilitate intrinsic motivation and learning achievements. For the application of exer-learning games, the concept of HOPSCOTCH is introduced that is inspired by the popular childrens game. Two demonstrators of this concept have been realized and evaluated: HOPSCOTCHpad and HOPSCOTCHmobile. First results show a positive feedback from scholars and teachers. Finally, future directions for our research on HOPSCOTCH are described that could model research on exer-learning games as well as their application in the classroom.
