Practice That Sticks
Why we revisit topics over time
Research shows that spacing math practice out over time and returning to each topic every few weeks builds far stronger retention than cramming.
Little and Often Wins
Cramming feels productive, but the memory fades fast. When practice is spread out over days and weeks, the same material sticks far better and for far longer.
That is why Matarus brings students back to each topic on a schedule instead of covering it once and moving on.

Distributed Practice in Verbal Recall Tasks: A Review and Quantitative Synthesis
Cepeda et al. (2006)

This large review combined the results of many studies on how the timing of practice affects memory. It found that when people space their learning out — returning to the same material after a gap of days or weeks — they remember it far better and for much longer than when they cram it all into one session. For math, that means coming back to a topic again and again over time locks it into memory, so skills a child learned months ago are still there when they need them.

How We Space Practice
Our platform tracks what each student has learned and schedules a return to it every few weeks, right before it would start to fade.
The result is math that stays available months later, not skills that vanish after the test.
