# Day 113 · Connect two choices

“Join this button to that page.”

## Set up

Author the two rules that the software/paper operator will follow. C05 is a fictional museum with MAP and MODEL pages, not a real map. Prepare START, PAGE A, PAGE B and two blank link strips. 20 minutes in pieces.

Use scrap paper and three broad cards, or a familiar locally approved device. A short chosen part is enough. A wanted helper reads or constructs exactly as directed; name who chooses and who operates.

## Run the session

1. Read all C05 givens.

2. Child chooses which button opens which labelled page.

3. Complete both rule strips: “When [button], show [page]”; a helper may write the exact direction.

4. Read both links from source to destination.

5. Apply the two valid rules in the tool, then run one selection; on paper, a helper reads and turns that linked card.

6. Return and check the other branch, or retain it as not checked yet.

## Choose a route

- 113a: Select each destination in a visible labelled dropdown and Apply; the tool interprets the two rules.

- 113b: Lay broad rule strips between picture cards; a paper operator traces the chosen link, even if cards are in a different position.

- 113c: Give a wanted helper an exact link instruction, then check the helper's read-back before operation. Each authors a relationship; card placement alone is not a link rule.

## Notice and next help

Two destinations can be different or deliberately the same if the purpose makes sense. If a link is missing, show the tool's plain incomplete-rule message, complete one missing relationship and re-read; don't invent output from an un-applied edit.
