Level ladder: move up after three clean sheets
For parents who want a clear daily plan. Your child works on one level at a time; three sheets with every answer right and under the target time, and the next level opens. Free, no sign-up, and the progress stays on this device.
How to use it with your child
- Tap Start level 1 (or the level shown). It opens the right tool with the level's settings already chosen.
- Tap Start on this device there and hand over. A sheet counts when every answer is right first time and the time is at or under the target.
- After a sheet the result card shows the dots: three filled dots pass the level, and a button takes you to the next one.
- Choose Relaxed if the targets feel too quick: every target becomes 1.5 times longer. Print sheet gives a paper ladder chart to tick off.
Which school years it suits
Years 1–6 (P1–P6, 小1–小6, 초1–초6). Levels 1–6 suit Years 1–2, levels 7–12 Years 2–3, and the column-sum and fraction levels Years 3–6.
Why three clean sheets
One fast sheet can be luck. Three in a row with every answer right shows the skill is settled, so the next level builds on something solid. The targets are our own suggestion, not a school standard; slower is fine, and Relaxed is one tap away.
Wrong answers never move a child down. A sheet that isn't clean simply doesn't count yet.

Questions parents ask
Where is the progress kept?
Only in this browser on this device, like the personal bests. It isn't sent anywhere. Clear this device deletes it.
Can my child skip a level?
Yes. Every level has its own button, so you can start wherever suits your child. The ladder only suggests the first level not yet passed.
Do printed sheets count?
The dots only fill from sheets done on screen, because the page needs the time and the marking. Print the chart to tick off paper sheets by hand.
