DreamBox Learning just launched with a K-2 math curriculum. While most educational software leaves something to be desired, DreamBox provides deep and individualized instruction that kids actually find fun. My kids have been beta testing it for several months and continue to ask to play. Hard to think of a better test than that. From an industry perspective, it is interesting in that it is a Web service with a subscription business model and has an extensible architecture upon they can offer other curricula. Nice work Ben and crew.
