Elements (and Algebra, also from Dragonbox) are my favorite educational apps ever -- and I say this as someone deeply skeptical about the claims made about technology and teaching. These games don't simply animate worksheets or offer conventional gameplay as a reword for doing work, they make the very process of doing math into a game. Brilliantly conceived and entertaining even for this 47-year-old, who found both to be a helpful refresher course in their respective topics. Granted, there are a few design tweeks to recommend; I found Elements somewhat less intuitive than Algebra. But overall these games are head and shoulders above any other math games currently out there (most of which are similar in all but the details). These games are special, ya'll.
