Attention spans by age: planning lessons around real children

The working table

• Age 3–4: 3–6 minutes per activity. One 'big' game per lesson maximum.
• Age 5–6: 5–10 minutes. Two-phase games work now (deal, then play).
• Age 7–8: 10–15 minutes with a clear goal; explanation budget: 60 seconds.
• Age 9–11: 15–20 minutes; they can hold multi-rule games and mini-projects.
• Online: multiply everything by 0.7 — the screen taxes attention before you say a word.

Signals you've run past the limit

• The eyes leave the screen before the hands leave the task.
• Answers get faster but sloppier — the child is buying exit with speed.
• The chair becomes a gymnastics apparatus.
• Any of these = switch NOW, not after 'one more example'.

Design tricks that stretch focus honestly

You can't lengthen attention by demanding it — only by re-hooking it. Games do this natively: every turn is a fresh hook. A 12-minute Memory game is really twenty 30-second attention loops; that's why a five-year-old 'can't focus for two minutes' on a worksheet but plays Memory for a quarter of an hour.

What the research actually says (and what it doesn't)

The famous classroom formula — 'two to five minutes per year of age' — has a secret: we could not trace it to any primary study, and neither, apparently, can anyone else. It circulates through parenting sites and training courses as received wisdom. It happens to point in a sensible direction, but treat it as folklore with good instincts, not measurement.

What HAS been measured: Ruff and Lawson followed children through their first five years and found focused attention grows steeply with age — and depends heavily on what the child is doing (Developmental Psychology, 1990, vol. 26, pp. 85–93). And Godwin and colleagues, observing elementary classrooms across a school year, found on-task behaviour DECLINES as an activity stretches from ten minutes toward thirty, with whole-group formats scoring the lowest attention of all (Learning and Instruction, 2016, vol. 44, pp. 128–143).

The practical translation is exactly what this article's table does: short activities, switched often, interactive over frontal — with the exact minutes tuned to your class rather than to a formula nobody ever measured.
