Closest Wins

Closest Wins is an estimation mode in LuLinDingo. Instead of asking your child for the exact answer, it asks "about how much?" and rewards a good ballpark guess. Getting near the right number counts as a win.

Why estimation matters

A lot of everyday math is estimation, not exact calculation. Is 30 euros enough for these groceries? Will this trip take about two hours or about four? Kids who can size up a number quickly have a feel for whether their exact answers later make sense. If a child works out that 312 plus 489 is 80, a good estimate tells them right away that something is off.

That sense of "about how much" is what Closest Wins practices. It builds number sense and rounding without making your child sweat over the last digit.

Where it shows up

Closest Wins is an extra activity, not a step your child has to pass. It appears as an "Estimation Challenge" button on lessons they have already finished, so it is always something familiar they are revisiting.

It is offered for the older age groups, roughly 8 and up, where the numbers are large enough that estimating actually helps. It covers addition, subtraction, and multiplication. Division is left out for now, since its answers don't round as cleanly.

How a round works

The questions use the same kinds of problems as the normal lesson, but bigger, into the hundreds and thousands. Each question shows up one of two ways:

The first is a choice between a few rounded options, like "about 600" or "about 800". Your child picks the one closest to the real answer.

The second asks them to type their own estimate. Here they don't have to be exact. Any answer that lands within a sensible range of the true number is counted as correct.

A round mixes both styles. Either way, after each question the app shows the rounded ballpark and the exact answer side by side, so your child can see how their guess lined up.

It is meant to be relaxed

Closest Wins is a low-pressure bonus round. Your child won't lose any hearts on it, and there's no score to chase. The aim is practice and confidence with "about how much", so a child can try, miss, and try again without anything riding on it.
