It may cost $5.99 to download, but DragonBox+ succeeds where many modern mathematics lesson plans fail. It simplifies the process of solving algebraic equations and even makes it fun for children. While the game is certainly designed for the young ones, there's no question that it can be used to teach teenagers and even some adults who may be seeking a better understanding of the sometimes scary subject.
When you first open up the app, DragonBox+ asks you to pick an avatar. From there, the first few levels act as a sort of tutorial, establishing a few rules and helping you get the hang of moving pieces on the board.
The entire game revolves around a single objective: isolate the glowing box on one side of the screen. With small pictured tiles strewn about on both sides of each level, it is your job to follow the rules of the game (new rules are added in each chapter) in order to move the tiles to the side opposite the box. In the first chapter, the levels are relatively simple, as they have only a few established rules and there aren't yet an overwhelming number of tiles. In the later chapters, however, things get more complicated.
If you haven't figured it out by now, the glowing box represents the variable that needs to be solved for, the "X" if you will, while the other tiles represent numbers. Since your job is to move the other tiles away from the box, you are essentially isolating the variable on one side of the equation and therefore finding its value.
