Times tables have to come from memory. A sum you work out is a sum you don’t know yet — and a drill that only checks the answer can’t tell those two apart, so it keeps marking “known” things that are still being counted on fingers.

So this one times the answer. Correct within six seconds moves the sum up a box; correct but calculated leaves it where it is; wrong sends it back to the start. Six boxes, waiting one, two, four, eight, sixteen and thirty-two days. From box five it counts as memorised.

The cap matters as much as the schedule: at most six new sums per session. Without it, a fresh table drops twelve unknowns at once and not one of them sticks.

Four ways to practise — Learn one table at a time, Practise a normal set of twenty, Hard for the ones that keep snagging, and Time for as many as possible in sixty seconds. Answers by button, or out loud where the browser supports it.

The scheduling model is lifted straight from the French drill in the same household; counting answer time is the only real difference.
