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.
Keep a true twenty-and-four account and give another. Use 24 safe pieces or original marks. A supplied ordinary teaching account is 20 + 4 = 24; inspect its members, then choose another valid split of the same whole. A job may suit unequal parts.
Show what each part contains.
Check that every object has one place.
Choose a split that suits this job. Show a reason and a possible revision.
Grown-up help
[Full daily plan](../teacher/day-48.md) gives today's exact reasoning and next instruction. This is an ordinary practice model, not a reserved fresh answer. If the total is too large, choose and label a smaller actual collection while keeping the partition purpose. Adult movement follows the child's decisions. Supplied counts are support, not evidence of independently finding that count. 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.
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.
