This chapter focuses on the use of a tablet game in a school setting to learn algebra. The positive results recorded in 142 out of 164 studies, with only one study having a negative outcome of mobile learning, can be interpreted as a mix of technology suited for learning, a Hawthorne effect, and pure optimism on the part of the new inventions. The study reported in the chapter focuses on the use of a tablet game in school setting to learn algebra. DragonBox is an algebra game for tablet computers discussed in the chapter. An approach related to stealth learning, known by Habgood and MPJ Ainsworth as intrinsic integration, is the idea of designing the game in a way that puts the essentials of the learning content in the critical parts of the gameplay. Playing games in math can be seen as an alternative for lower-achieving pupils, providing an alternative method to teaching and solving regular algebra.
