Why does frequency beat duration at this age?
Two reasons, and they compound. The first is attention: a 7 year old’s productive concentration on deliberately difficult work runs in the range of fifteen to twenty-five minutes, after which additional time produces effort without learning. The second is spacing: recall is strengthened by retrieving something after a gap, so five short sessions across a week create five retrieval events where one long session creates one.
What does a realistic week look like?
| Situation | A reasonable week |
|---|---|
| Keeping up, no known gap | 15–20 minutes a day, four or five days |
| One specific weak skill | Same daily practice, weighted towards that skill until it moves |
| Meaningfully behind | Daily practice plus a weekly session with a tutor, for a defined stretch |
| Diagnosed learning difficulty | Whatever the specialist recommends — this is not a scheduling question |
How do I know if it is working?
Give it six weeks and look for movement in the specific skill, not in a general feeling. Accuracy on that skill, and whether it holds after a week away, are the two things worth tracking. A rising overall score with the original weak skill untouched is not progress; it usually means practice drifted towards what was already easy.
Missing days does not undo it. The thing that ends progress is stopping altogether, which is usually caused by sessions that were too long rather than too easy.
