# Your little maths help desk

Year2 Mathematics · Term1 Weeks9–10 · planning Days41–50.

Choose a useful question, make something that helps, and check what it tells us. Ten complete lesson plans and small home offers are ready for source review. This is a finite author source delivery awaiting a different reviewer, not native/site/grade/state approval.

- [Child · choose one little turn](child-start.md)
- [Parent · one useful offer](parent-start.md) / [all ten tiny home offers](family/README.md)
- [Teacher · preparation and next teaching](teacher/PREPARATION.md)
- [Ordinary complete sources](MATERIALS.md), [twenty worked life contexts](CONTEXTS20.md), [thirty participation routes](ROUTES.md), [ten larger/extra choices](EXTRAS10.md)
- [Original models and real own blanks](aids/README.md) / [full no-image alternatives](aids/ALTERNATIVES.md)
- [Adult real facts/local replacement](FACTS-AND-LOCAL.md), [full104 record national scope/mapping](curriculum/MAPPING.md), [complete portable notices/grants](legal/NOTICE.md)
- Staff only: [held first/later/reserve guide](assessment/README.md), [complete independent keys](teacher/KEYS.md). Do not send those or recipe.json to ordinary child/home practice. Select only the intended full source/own blank; reserve sources remain unseen.

## Edit, reproduce, review

Change an owned recipe.json copy, retaining actual source/date/component/rights. Python3 standard library can recreate the complete source in a new empty owned location: `python3 -B build_source.py --output /new/owned/source`. Default read-only check: `python3 -B verify_source.py`. Full raw authority remains exact; new extraction needs actual workbook/canonical reconciliation, not guessed cells. Complete [developer instructions](DEVELOPER.md) distinguish a successful semantic check from personal use/teaching outcomes.
