Teachers should expect wide normal variation and watch the broad pattern across fine-motor play, referring for a check if a child consistently lags peers.","answer_md":"*A tower of bricks is more than play — it is a child showing you their hands, their eyes and their patience all working together.*\n\n## In short\nMost children stack two blocks by around 15 months, a tower of about four to six blocks by two years, and eight or more by three years. By three to four years many can copy simple structures like a train or bridge. In class, expect wide normal variation — a teacher's role is to notice the broad pattern, not to chase exact numbers.\n\n## What to expect in class\nBlock stacking is a window onto **fine-motor control, eye–hand coordination and concentration** (ICF domain d4, mobility and hand use). At each stage you might see:\n\n- **15–18 months** — stacks 2–3 blocks, often knocks them down with glee\n- **2 years** — builds a tower of 4–6 blocks, beginning to line some up\n- **3 years** — stacks 8+ blocks, starts copying a simple model\n- **3–4 years** — imitates a bridge or train, shows planning before placing\n\nA child who finds this far harder than peers — persistently unable to release a block accurately, very frequent toppling with frustration, or avoiding the activity altogether by age three — is worth a gentle developmental check. Look at the *whole* pattern across drawing, feeding and dressing too, and remember left-handed, premature or simply cautious children may take their own route there.\n\n## The Pinnacle way\nA clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care — never from a single classroom observation.
