Paper parcel rule labYear 10 Subjects · T1 W3–4 · Interactive activity
This offline practice tool uses invented label states only. It sends and stores no input. READY needs readable AND reviewed. An unknown value asks for a data check; it is not silently changed to NO. This is not a real parcel, booking, borrowing or security system.
Predict, then test
Write or say your expected result first. Choose the two fictional input states and run both rules.
Known-value cases to test
| Readable | Reviewed | Expected AND | Faulty OR |
|---|---|---|---|
| Yes | Yes | READY | READY |
| Yes | No | NOT READY | READY |
| No | Yes | NOT READY | READY |
| No | No | NOT READY | NOT READY |
Unknown in either input → CHECK DATA under this teaching policy. This early branch asks for missing information before applying the yes/no rule.

Content means the words shown to a reader, such as “Paper parcel rule lab”. Structure uses markup, such as <h1>Paper parcel rule lab</h1>, to identify that text as the top heading. Presentation uses CSS, such as h1 { color: #173b50; }, to change appearance without changing the heading's words or meaning. The page still works in plain text through the full text route.
