Times table practice that grows with a child

A worksheet of a hundred mixed times table sums is a warm-up for one child and a wall for another. This tool starts at the first three tables, the ones and twos and tens, and only widens once a child shows it has those tables down: enough sums right, answered quickly enough.

That happens on its own, with no number that reads like a school report. A practice level says what a child can do fluently today, and is not a judgement of how good it is: this is a practice tool, not a test.

If a child slips back on a table for a while, the practice level moves back with it. The tool simply changes the line to say so; there is no red screen and no message.

Not every moment calls for a child's own practice level. A teacher who wants the whole class on the eight times table, or a child who wants another go at one awkward table, presses "Choose your own" and ticks the tables the tool may ask.

That free practice still earns points, the same as an ordinary round, but it never changes the practice level: a child who deliberately ticks the easy tables cannot practise its way upward that way. Without an account the tool only works this way, as a plain times tables trainer with no practice level of its own.

Every sum that is typed is kept against the child's account: right or wrong, and how long it took. That is how the tool knows which sums still take effort, so those come up a little more often than one that has long been quick.

That history belongs to the child. It disappears on its own after a year, the same as the other practice rounds on Reppilo, and a teacher never sees more than where a child stands on the tables.
