How spaced repetition works for times tables

Each times-table fact gets a review just before it would fade. Gaps grow when recall holds.

What the schedule is doing

Every multiplication fact carries its own interval and strength. A new fact comes back in seconds. 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.

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.

  1. 7 × 8
  2. 20 seconds
  3. 40 seconds
  4. 1 minute
  5. 3 minutes
  6. 1 day
  7. 3 days

A correct 7 × 8 might wait days. A miss shows up again in the next session or two.
