Dragon Box is a math app unlike any we have ever reviewed. Algebra is presented with images leveled through concrete steps for kids who are not yet able to understand or perform basic operations from addition to division. What is amazing is the way that algebra is broken down into small graphic patterns that are easy for kids to master and repeat. There is no discussion of why or how everything works, but the rules are presented in a completely scaffolded way that kids love to return to and keep mastering. A wonderful app to have, check out Dragon Box+ to get the full version with an additional 100 levels.
