Teacher copy: This page may include teaching prompts or answer keys. Answer keys in this public library can be viewed by anyone. Give learners a clean prompt, use checks as formative evidence, and change a case locally when prior access matters.
Make a corrected, checkable quantity note. Choose safe pieces, marks, tactile objects or tell an adult where to move them.
Show the whole and each part.
Try another split using the same objects.
Check what stayed the same. Keep a useful plan or change it.
Grown-up help
[Full teacher plan](../teacher/day-48.md). If every claim is changed, show a new valid and invalid small pair without error cues. If the reason is only looks wrong, match each claimed object to actual members before changing a label. Use local safe materials and usual communication/access supports. Child-directed adult physical work and child mathematical choice stay distinct. Preserve first thinking before feedback; a drawing is not an actual outside inventory or performance event.
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.
