Guess my X and other techno-pedagogical patterns: toward a language of patterns for teaching and learning mathematics

Most people see learning mathematics as a demanding, even threatening, endeavour. Consequently, creating technology-enhanced environments and activities for learning mathematics is a challenging domain. It requires a synergism of several dimensions of design knowledge: usability, software design, pedagogical design and subject matter. This paper presents a set of patterns derived from a study on designing collaborative learning activities in mathematics for children aged 10-14, and a set of tools to support them
