How Long Should an Activity Last?

By Hellen Gomez, founder of Montessori Kids•October 29, 2026

Stop watching the clock

A four year old might work for forty minutes on pouring and four minutes on a puzzle. The work is not the time. It is the attention.

Signal one: repetition

If your child does the same action again and again, the activity is working. Do not interrupt it to move on. Repetition is the child practising a skill they are still forming.

Signal two: the wander

Looking up, touching something else, lying down. That is finished, even if the tray is not complete. Let it end there and put the tray away together.

Signal three: the escalation

Throwing, banging, sweeping pieces off the table. This is usually fatigue rather than naughtiness. End the session, do not correct the behaviour as if it were a choice.

Signal four: the natural pause

Sometimes a child sits back and looks at their work. Wait ten seconds before saying anything. They often return to it. If they do not, they are done.

A workable range

Ten to twenty minutes is common for ages three to five, longer when the material is new. If sessions are consistently under five minutes, the activity is probably too hard or too easy.
