Looking for a game like interface that presents math facts starting at basic concepts like "1 + 1" then models the childs fluency, or lack of, and uses that data to present questions. Errors should be corrected as they're made; doesn't require an explaination, even just a error-buzz sound and a reseting of selected. Game wise it the game should present a charted preformance based on past preformance.
Open to other approaches, just believe the system above is what I'm looking for.
