Educationally sound and challenging math drill practice – FlowPlus: Add. Subtract. Enter the Flow. Review

Educationally sound, quick-paced drill game. Fun music and sound effects. Settings allow you to shut off background music, sound effects, stats and tutorial feature independently of each other, which is awesome. I would love a feature that allows unlimited time for answers, however-this would make it more friendly for certain populations of students.
