# Public teacher-targeted worked key and next moves

The key is **public by URL** and the checks are **not secure exams**. Collect first child-controlled responses before feedback. If prior exposure matters, prepare and key another invented source. Record reading/scribing/access separately from an adult content cue. No child's actual name, image, voice or account is collected. Data representation from paper can sample K02; **K01 actual digital exploration is not observed** from either check. A category-level privacy choice samples P01 only partially and is not a legal ownership judgment.

## Check A · Day 5 · Exact new source and answer

The [Paper Costume Rack source](../print/check-a-fresh-rack.pdf) prints **HAT, HAT, BAG** left to right. It therefore has **three entries**: **two HAT** and **one BAG**. Three broad physical tokens represent entries in that order; the picture record is **hat outline, hat outline, bag outline**; the agreed symbols are **H H B**. Accept child-controlled alternative symbols only if the child provides a consistent key, preserves order/categories and uses the same key across the work. For an initial response to these printed category labels, H H B is the direct key. First symbol traces to first HAT; last B traces to BAG.

The two blank cards read **MY NAME (not written here)** and **PLAIN CIRCLE ICON**. If a card contained the child's own name, that could be personal data about them; the value is **not present or requested**. The plain circle icon is a neutral invented mark. Record only the category choice, never a real name. This is not an instruction for public disclosure.

| First response | Next teaching move |
| --- | --- |
| Three physical tokens, hat/hat/bag pictures, H H B in source order, first/last trace and empty MY NAME category recognised | Use a new neutral three-entry source later; record this as one partial K02/P01 sample. |
| Correct two/one count but symbol order B H H | Align each source word with one token, picture and symbol slot before repeating the new set. |
| Symbols given without a key | Ask “What does this mark mean for this source?” and record the child's key. |
| Child begins to offer an actual name | Stop transcription and reassure that only the empty category is needed. |

## Check B · Day 10 · Exact new source and answer

The [Paper Parade Box source](../print/check-b-fresh-props.pdf) prints **FLAG, ROUND TOKEN, ROUND TOKEN** left to right. It has **one FLAG** and **two ROUND TOKEN** entries. Physical token order and picture record follow **flag outline, round token, round token**. With the source's agreed first letters, the symbol line is **F R R**. The puppet's **F F R** is wrong at the **second position**: the second source item is ROUND TOKEN, not FLAG. Its count is also wrong (two F and one R rather than one F and two R). Correct the first mismatch and then check all three positions.

The empty cards read **MY FACE PHOTO (not shown)** and **PLAIN TRIANGLE ICON**. A real photo of the child's own face could be personal data about them; none is on this page or requested. The triangle is a neutral invented mark. Accept a private point/sign/AAC response; record only the category.

| First response | Next teaching move |
| --- | --- |
| F R R aligned to source, second-position puppet error identified, own-photo category recognised without disclosure | Transfer to another neutral invented set; keep actual device exploration separate. |
| Puppet copy judged correct because it has three letters | Compare category counts and each indexed source entry, especially the second. |
| Child uses another consistent symbol key | Let child state the key, then check every position with that key; do not score a valid agreed key wrong merely for different letters. |
| A child claims a print/page is a digital system they used | Clarify that a printed representation is not an actual running device; plan an approved real-system observation later if appropriate. |

**Claim boundary:** Both public checks can sample K02 and P01 partially. They do not assess K01 actual system exploration, secure privacy handling, a real child data decision or complete Prep Digital Technologies attainment. Follow the locally adopted curriculum, school device and privacy policies for authentic evidence.
