N23 · Silent scene board

Id

N23

Original component

B-later-Q3

Target criterion

A complete orthogonal route starts at A4, stays inside the grid, avoids B4 at every step and ends at D2; no shortest-path requirement.

New job title

Silent scene board

Source

Fictional paper scene: Silent scene board. There are 4 columns A to D, left to right, and 4 rows 1 to 4, top to bottom. All cells have the same size. Up/down mean towards the top/bottom of this page; left/right across this page. One move reaches one neighbouring cell, never a diagonal. Start: A4. Target: D1. The name-card is at A1; the spare-card is at D4. Closed cells: B4. Do not enter or pass through them. Proposed instruction: 3 cells right, then 3 cells up. This is a supplied scene. Read its whole legend before the questions; it is not a real place, a measured route or an observed journey.

Mathematical data

Invitation

Create a complete safe route from the supplied start to the target; list each amount and direction.

Teacher moves

On separate teacher work for Silent scene board, plan a vertical-then-horizontal route and replay every cell. Name all amounts and directions; show that every visited cell is inside/open. Then accept a different complete legal route. A shorter route is not a separate criterion.

Worked possible response

3 cells up, then 3 cells right; positions A4, A3, A2, A1, B1, C1, D1. This stays inside. The stated closed cell is avoided.

Guided source

Fictional paper scene: Silent scene board—new guided scene. There are 3 columns A to C, left to right, and 4 rows 1 to 4, top to bottom. All cells have the same size. Up/down mean towards the top/bottom of this page; left/right across this page. One move reaches one neighbouring cell, never a diagonal. Start: A4. Target: C2. The name-card is at A1; the spare-card is at C4. Closed cells: B4. Do not enter or pass through them. Proposed instruction: 2 cells right, then 2 cells up. This is a supplied scene. Read its whole legend before the questions; it is not a real place, a measured route or an observed journey.

Guided data

Guided invitation

Create a complete safe route from the supplied start to the target; list each amount and direction.

Guided staff possible response

2 cells up, then 2 cells right; positions A4, A3, A2, B2, C2. This stays inside. The stated closed cell is avoided.

Receive own steps

Read/hear the whole new source and name the actual requested job.

Receive the learner’s own idea in their usual communication before the staff response.

Teach the precise relationship using the separate complete model; name mathematical hints.

Deliver the complete different guided source and invitation. Receive a fresh response before its staff possibility.

Review criterion

Gives a complete replayable legal route with amounts/directions and checks all visited cells.

Observe and next

Record the exact relationship available in the response and the help, leaving absent evidence open. If it is missing, repeat that same relationship on a smaller complete source. If secure, change the scene/quantity or representation explicitly; do not infer annual mastery.

Access

Point, speak, sign, AAC, tactile labels, large marks or exact child-directed scribing/moving. No speed, handwriting, robot, printing or public sharing criterion.

Transfer limit

Different supplied complete new and guided contexts; no remembered original held source or real learner improvement is claimed.
