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 two packing plans for the same thirty-two marks. Choose safe pieces, marks, tactile objects or tell an adult where to move them.

Grown-up help
[Full teacher plan](../teacher/day-45.md). If both versions remain, mark the ten represented objects and remove their old strip as the singles replace it. If the whole changes, count a new smaller account before/after one exchange. 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.
