Description

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

Xubri Subtraction provides practice for the subtraction facts 0 - 0 through 18 - 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 Subtraction is designed to work well in classroom settings. 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 subtraction 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 subtraction facts can focus all of their mental resources on the math problem at hand instead of diverting some of their mental resources to finding subtraction 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.

Fighting summer loss

So far, we're pleased. As the school year winds down, we wanted to get her started on something fast and simple that could help her maintain basic math facts. She likes working 10 minutes and getting to go back to her preferred summer vacation tasks, and we like the knowledge that she's maintaining (and perhaps improving) her basic math skills. The new update allows you to delete students.
