A practical clinical reference for pediatric OTs working on pre-writing skills — stroke progression, sample goals, grading strategies, caregiver coaching, and documentation language.
| # | Stroke | Typical age | Level | Letters it enables |
|---|---|---|---|---|
| 1 | Vertical line ( | ) | 2 – 2½ yrs | Emerging | I, T, L, H, E, F, P, B, D, R, K |
| 2 | Horizontal line ( — ) | 2½ – 3 yrs | Emerging | T, L, H, E, F, A, Z |
| 3 | Circle ( ○ ) | 2½ – 3 yrs | Emerging | O, C, G, Q, a, c, d, e, g, o, q |
| 4 | Cross / plus ( + ) | 3 – 3½ yrs | Developing | T, F, E, H, f, t |
| 5 | Right diagonal ( / ) | 3½ – 4 yrs | Developing | A, K, M, N, V, W, X, Y, Z, k, v, w, x, y, z |
| 6 | Square ( □ ) | 4 – 4½ yrs | Consistent | Prerequisite for all four-sided letter forms |
| 7 | Left diagonal ( \ ) | 4 – 4½ yrs | Consistent | M, N, W, X, Y, K, R, Z |
| 8 | Triangle ( △ ) | 5 – 5½ yrs | Advanced | A, V, W, X — and complex pencil control |
| Variable | Grade Down (easier) | Grade Up (harder) |
|---|---|---|
| Guide band width | Wide band (½ inch+) — lots of room for the pencil to wander | Narrow band (⅛ inch) — demands precision and control |
| Line length | Short lines (2–3 inches) — less sustained control needed | Long lines (full page) — builds stamina and wrist stability |
| Task type | Tracing over a printed line — visual feedback as they go | Copying from a model — must hold image in visual memory |
| Model distance | Model right next to copy space — minimal memory load | Model on board or across the room — increased working memory demand |
| Writing tool | Chunky crayon or short pencil — promotes tripod grip naturally | Standard pencil — full fine motor control required |
| Surface | Vertical surface (whiteboard) — reduces wrist extension demand | Horizontal desktop — full wrist stabilisation required |
| Number of strokes | One stroke at a time — reduces cognitive and motor load | Multi-stroke design or letter — requires planning and sequencing |
| Visual cues | Numbered arrow cues showing start point and direction | No cues — child must recall formation from memory |
