Building on the assumption that mobile learning has a positive effect on student attitudes and academic outcomes including STEM subjects (Hsi, 2007; Wu et al., 2012) we develop a theoretical lens for future studies for ‘mobile mathematics’. The two case examples describe how mobile technology could provide opportunities for ‘mathematics outside the classroom’. The first example describes a dynamic Ferris wheel, the second a static cathedral. Both examples demonstrate how ‘geo-location’ and ‘augmented reality’ features allow mobile technologies to bridge formal and informal mathematics learning (Lai et al., 2016). %T Augmenting Mathematics with Mobile Technology %O This version is the author accepted manuscript.
