# Day 199 · Give it an explanation worth using

**Learning job:** Communicate the display job and a useful first instruction; keep local-source/recipient claims bounded.

**Have ready:** Private self-use or one willing person; no sharing, trip, photograph or household report requirement.

**Say to the child:** What would help you or a willing person use your display? Keep your own words. A reply is optional.

1. Choose what the own explanation should help someone do. Private self-use is a complete option.
2. Keep purpose, chosen face/form, first material/step and one open question before models.
3. Use a route. A recipient’s exact reply is recorded only if actually supplied; no reply is useful evidence of an unanswered question.
4. After capture, read C17/C18’s narrow offered reply and unshared guide. Neither becomes proof about every visitor.
5. An adult may complete the local source review fields for F1/F2. The real provider note is not an observation of this learner, universal material approval or maker-intention account.
6. Retain the usable explanation. D-first requires actual source-status and familiar-example teaching and may be postponed beyond this sequence.

**Choose one route:**

- Make a broad picture explanation for yourself showing the display’s purpose and first action.
- Give usual-communication directions to one willing person and retain only their actual offered words.
- Ask an adult to review one local factual note while creating an original invented display plan; no child browsing.

**Look for / next teaching:** Own communicated design and source/reply limits. Next teach a reply’s exact scope with an unrelated fictional instruction.

**More choices:** C17/C18, H09, X09. Keep models after the first idea.

**Read together:**

You can keep a picture guide for yourself. If somebody agrees to look, ask one useful question and keep their real words. A museum page says something about the museum; it doesn’t say our display has been tested or that you visited. We can leave questions unanswered.
