The availability of computer technology in educational institutions offers opportunities for the implementation of augmented spaces for human-computer interactions. We can observe the increasing adoption of technology such as computers, wireless networks, and electronic whiteboards in schools to support teaching activities. Whereas it is plausible that schools use technology to reinforce learning, we think there are other educational activities being set aside. This article presents two works in progress: The Game of Pirates and The Virtual Maze. The Game of Pirates is a game which aims to encourage physical activity, therefore it addresses childhood obesity. This game asks children to engage in vigorous physical activity in order to obtain the keys that open the treasure chest. The Virtual Maze is a resource that can be used to promote children's teamwork. Two children, the main player and the collaborator, need to communicate, exchange opinions, and take joint decisions in order to traverse the labyrinth and complete the game. Current implementations are being tested in the laboratory and will be soon available to offer children of primary school age an experience with these kinds of mobile computing experiences.
