Review Excerpt: The first part of a two level algebra game, DragonBox Algebra 5+ is an iPad app that turns simple algebra equations into a card game. The idea is to let children discover some of the key concepts behind variables and balancing equations. The game uses a mastery learning scoring mechanism, like Angry Birds, to present a series of progressively more challenging puzzles where you combine cards in order to balance equations. If you mix and match well, you earn more stars. The goal? “to secretly teach algebra.” Subscribers, please log into our database using your password to read the full review along with our rating, and see why this received our Editor’s Choice Award.
