Target/codes: Place an undated pictorial source outside a known source order and ask a useful time question; AC9HSFS01, AC9HSFS02 and AC9HSFS04 partial. Ready: C, separate pocket, TIME NOT RECORDED tag, A/B.
Child product: Undated-source pocket kept beside the two known time windows. Real-place option: R3; AC9HSFK03 conditional sourced personal-significance opportunity.
- Open · 3 min. Show C without adding a time label. Ask “What can this picture tell? What is missing?”
- Read source · 4 min. Read C including “Time not recorded.” Say its maker/time are unknown in this set.
- Model · 5 min. Put C in its own pocket, not first/last. Show that its basket location matches A but doesn't prove C was made earlier or is currently correct.
- Child inquiry · 7 min. Play map-post sorter: child attaches C's pocket beside the known trail and adds a “When was this made?” flap. Let the child test two possible positions for C, then return it to TIME NOT RECORDED because neither is established.
- Check/respond · 4 min. If different pictures become a lie accusation, explain “Maybe different times; we need a time source.” Do not supply a date.
- Exit · 2 min. Child names one C feature and one unknown. Next move: add a named later visitor view.
