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.
Label two verified ten-strips and four singles. 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.

[Full daily plan](../teacher/day-44.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 a child says five for three strips plus two, open one strip, touch its ten marks and label the object value. Then use a new two-strip model before returning to three strips.
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.
