Fact Vault

As your child plays, LuLinDingo keeps a quiet record of how well they know each individual fact, like 7 x 8 or 9 + 6. It learns this from their normal answers. You don't set anything up, and your child never sees a quiz or a test for it. It just watches and remembers.

How weak facts come back

Facts your child gets wrong come back sooner. Facts they answer well come back less often, with bigger gaps between each look. A fact they keep getting right might not show up again for a couple of weeks, while one they miss returns the next day.

This is spaced practice: instead of drilling the same sums over and over, the app times each fact so your child sees it again just as it's starting to fade. A wrong answer drops a fact back down so it resurfaces quickly. A run of correct answers pushes it further out.

The point is to catch the shaky facts without nagging your child about the ones they already own.

Where you'll find Review and Practice

When some facts are due for another look, a soft card appears at the top of the home screen with a count, something like "5 facts to review." Tapping it starts a short Review lesson built from those due facts. The card only shows up when there's actually something due, so an empty home screen means your child is on top of things for now.

Next to it is a "Practice for you" option. This builds a short set aimed at your child's current weak spots, and it's there whenever they want it, not only when facts are due.

No pressure

Review and the targeted practice both run in practice mode. That means no hearts are at risk and no XP is on the line. If your child misses a fact here, they don't lose anything. These sessions exist to give shaky facts another turn, not to score your child.

Their normal lessons, stars, and streak all carry on exactly as before. Fact Vault sits alongside that and works on its own.
