The Numelu method: See → Try → Understand
Most maths apps tell a child “right” or “wrong”. Numelu is built around a different question: what did the child think, and what picture will fix that thought?
A picture before a rule
Every task comes with a model the child can look at and touch: objects, ten frames, a number line, base-ten blocks, arrays, fraction bars, an area model. Children first act on things, then see the same idea as a drawing, and only then as bare digits. The same few models return from grade to grade, so new topics feel familiar.
Hands on, not multiple-guess
The youngest children tap objects to count them and tap the bigger group. Older children type the answer on a large keypad. Tasks are read aloud when the device has a voice for the language, so reading is never the barrier.
Build the answer
In many tasks the child does not pick or type a number at all — the answer is made by hand on the picture: fill the ten frame, cross out what is taken away, drag cookies onto plates, colour the parts of a fraction, build a number from rods and cubes, tap the right place on the number line. The picture stops being an illustration and becomes the tool for thinking.
Smart mistakes: we look for the reason
A wrong answer is information. Numelu recognises dozens of typical slips — counting one twice, adding instead of subtracting, losing a carried ten, taking the smaller digit from the larger, adding denominators, working left to right — and answers each with its own explanation: what probably happened, why it does not work, and what to look at.
The hint ladder
Help comes in small steps. The first hint only points at a strategy. The next one shows it on the picture. Only after that is the whole solution played, step by step, with the animation doing exactly what the words say. The child always gets the smallest help that is enough.
The twin task
Watching a solution is not yet knowing. After a solution is shown, the next task is its twin: the same idea with new numbers. The lesson ends on something the child did alone.
Check Numi: the roles swap
Twice in every session it is Numi who answers — and Numi sometimes slips in exactly the ways children typically do. The child decides whether the answer is right, reads what went wrong and puts it right. Spotting and explaining someone else’s mistake is safer than facing your own, and it is one of the strongest ways to understand.
A companion that grows
Stars are not spent and cannot be lost. They make the sprout on Numi’s head grow and open things for Numi to wear. The reward is care for a character, not a score to compare.
The right level, automatically
Each skill has several levels. Three clean answers in a row move the child up; two tasks that needed a full solution move back a step. The daily mix brings back skills that were hard or have not been seen for a while.
Calm and kind
No timers, no lives, no red crosses, no losing streaks. Stars are earned for thinking, including after a hint. A session is eight short tasks — a few minutes a day is enough.
