Everything produced by WeWantToKnow is fantastic. My kids love all the DragonBox apps (worth every penny), so I was so excited to see that they created an app for the younger crowd, because DB was a little too advanced for my 4-year-old. He gets his chores done every day and the first thing he asks me is, "can I do my math now?" And I am so happy to let him! I would give this app 10 stars if I could.
