How long does it take to learn times tables?
The honest answer depends less on how much your child practices and more on how practice is spread over time. Research is unusually clear on this, and the conclusion is more encouraging than most parents expect.
What the research says
The timeline depends less on total practice time than on how that time is spread out. A landmark study by Rea and Modigliani found that children who practised at spaced intervals remembered about twice as much as those who did it all at once, even with the same total time.
A 2025 meta-analysis of more than 3,000 students confirmed the advantage of spacing practice and recalling answers: an average effect of d=0.54, a meaningful and consistent advantage in real classrooms, not just in the lab.
What “a few weeks” means in practice: children who practise 3 to 5 minutes a day usually show measurable progress in the first week, and reach solid, reliable recall in 4 to 8 weeks, depending on where they start and how consistent they are.
What this means in practice
There’s no timeline that fits everyone, but the pattern is clear: children who practise a little every day learn faster than those who do longer, less frequent sessions, even if the second group adds up more minutes. Consistency beats intensity.
Try this
- Pick a set time each day, like after school or before dinner, instead of squeezing it in whenever.
- Note which facts are still shaky after two weeks. They need to be recalled more often, not re-read or repeated more.
- Don’t stop when your child “knows” a table. Without review, the memory fades.
