ProblemScape is an adventure game for introductory algebra. The game takes you to the strange city of Arithma in search of your lost sibling. You need help finding them, but who can help you? The inhabitants of Arithma, the Arithmen, are by nature helpful (that is, when they're not playing paintball). The mayor of Arithma can help too, but you have to find him first, which is not always easy - he goes into hiding at the first sign of trouble! It turns out the Arithmen need your help too. The only ones in Arithma who can do math, the Xperts, have all vanished! Could this be connected to the disappearance of your sibling? And how can a city function without anyone knowing math? The fun and engaging 3D adventure game includes videos/animations, worked examples, extensive practice, teach to learn activities that facilitate deep engagement and understanding, assessments for each concept, challenge games, and a narrative that promotes math efficacy and social-emotional development. The multimodal math content is deeply rooted in research, follows the "Expressions & Equations" strand of the Common Core State Standards, and is for anyone who wants to learn Algebra. There are eight chapters or levels in the game, with each chapter focusing on just one or two concepts. The game helps students get a robust understanding of variables, learn different strategies for solving one-step equations and inequalities, and explore dependent and independent variables.
