Engage students with adaptive addition practice that allows them to finish good practice fast.

Xubri Addition provides practice for the addition facts 0 + 0 through 9 + 9 at a pace that is customized to individual needs through adaptive practice sessions. The problems are presented in ways that harness the most recent research in cognitive psychology related to learning and memory. Individual progress is stored on the device, and students can pick up right where they left off after the last practice session.

Xubri Addition is designed to work well in classroom settings, too. Multiple students can set up accounts on the same device. Individual practice sessions are silent, avoiding classroom distraction. And, because practice problems are carefully chosen for each student, even just a few minutes of practice a day can yield gains. Finally, the time practiced over the last five days is recorded, so students can monitor if they've been consistently putting in adequate practice time.

Students who improve their mastery of addition facts can see improvements in other math tasks, too. When faced with new concepts or story problems that require addition, students who have mastered their addition facts can focus all of their mental resources on the math problem at hand instead of diverting some of their mental resources to finding addition solutions. Additionally, students who have mastered their basic math facts learn new math concepts with the confidence that the building blocks needed have already been mastered.

Just right

I wanted something that is low maintenance (I don't want my 5-year-old to always have to set up the practice by saying what numbers to practice.) Also, my wife (a teacher) wanted something simple and efficient (we'd rather have 5 - 10 minutes of solid practice than longer on a game that's educational.)

Very pleased! So is our daughter :)
