Prepare: Book and checked ruler, or MODEL book edge 16 cm and paper 20 cm.
Invitation: Estimate an edge, then measure or direct a helper if suitable. Decide whether a paper strip fits; otherwise compare the supplied model.
Adult worked model/check: Model 20 − 16 = 4 cm extra; real results stay as actually read.
Choice and boundary: No scissors needed. Fold/mark only if wanted; adult handles any cutting.
Usual communication, exact scribing, private/untimed work and stopping are welcome. Keep a model answer separate from your child's own attempt; do not correct it silently. Observe one useful reason and choose a new unrelated example if wanted.
Source review is complete for this two-week edition. Local suitability and classroom use still need review. Earlier candidate or pending-review words are retained in the original files; full-year coverage, translations and audio are not claimed.
Keep these complete conditions with PDF, SVG, text and ZIP copies. PDFs retain their full attached source and notice files; the downloadable packets keep their declared companions.
