# B-first · Who marked the wave?

## Whole story

Original fiction. Len chooses an invented wave mark and tells adult Ren where to put it on a whole paper sheet. Ren marks the wave and places the sheet flat. Len then describes a bend; no one makes that bend in this source. Nobody conducts a standing or viewing check. The source does not say that Len marked, folded or placed the paper. It gives no actual result about a folded display.

## Select after actual teaching

Actual actor/design/practical evidence distinction and exact step teaching; B3 additionally needs purpose-linked check teaching (Day196 or equivalent); B4 preference/result/unknown teaching. Select only individually taught components.

## Exact questions

1. Who contributed the design idea, who physically acted, and which proposed action remains unperformed in this source?
2. For an own wave-display idea, name a material, proposed actor and an exact action/location.
3. Choose one question and a suitable proposed check for your own display. What result is actually supplied here?
4. Choose a feature to keep or change in an own idea. Explain your reason and what remains unknown.
