How spaced repetition works for times tables
Language apps have used this for years. Times tables mostly still get worksheets. Review each fact right before it would fade, then wait longer the next time it holds.
What the schedule is doing
Every multiplication fact carries its own interval and strength. A new fact comes back in seconds, then longer gaps in the same sitting, then tomorrow, then a few days. A miss starts that short ladder over so it can be recalled again before the session ends.
A session then holds facts that are worth asking today. 3 × 2 stays out of tonight’s list. 7 × 8 comes back before a month of silence can wipe it.
Why this fits the times tables
The method works on many small facts that need to come back fast. The times tables are 121 items from 2 × 2 to 12 × 12, each a one-second retrieval, each with its own habit of slipping.
Most times-tables tools still run everything equally (worksheets) or everything randomly (games). Worksheets and games skip the dates. The dates are why 7 × 8 is still there in March.
What TimesOwl does
These 121 facts run in TimesOwl as a spaced-repetition deck. Typed answers, graded on correctness and speed. New and overdue items stay capped so a session does not balloon.
- 7 × 8

A correct 7 × 8 might wait days. A miss shows up again in the next session or two.
Try five minutes before the worksheet.
