Trace a Supplied Paper Route
A route combines direction vocabulary with sequence.
About 25 minutes, plus any extended practice
Supplied materials
- Paper or a browser scratch area; no audio recording, account or private information is needed.
- On an original paper grid, start at (0,0) facing north. Read: “Siga recto 1 casilla. Gire a la derecha. Camine 1 casilla.” Gloss: casilla=grid square; casillas=grid squares; siga recto=continue straight; gire=turn; camine=walk. North increases y; east increases x. Which endpoint follows the ordered instructions? Candidate answers: (A) (-1,1) (B) (0,2) (C) (1,1) (D) (5,3).
- On an original paper grid, start at (0,0) facing north. Read: “Siga recto 2 casillas. Gire a la izquierda. Camine 2 casillas.” Gloss: casilla=grid square; casillas=grid squares; siga recto=continue straight; gire=turn; camine=walk. North increases y; east increases x. Which endpoint follows the ordered instructions? Candidate answers: (A) (-2,2) (B) (0,4) (C) (2,-2) (D) (2,2).
Learn the idea
Location phrases and route instructions connect language with a fictional paper plan. The goal is to preserve spatial relationships and order, using the glosses supplied here; no real-world navigation or outdoor activity is required. A route combines direction vocabulary with sequence. Siga recto moves in the current facing direction, while gire changes that direction without itself moving to another square. The next movement follows the new orientation.
Mark the supplied start and north arrow on paper. Translate each instruction in order, recording an intermediate point after straight movement and a new facing arrow after the turn. Then apply the final number of squares in that direction.
These original grids supply their coordinate convention and all command glosses. Do not assume right always means east: it does here only because the initial facing direction is north. A turn changes orientation rather than adding an unstated step.
- Copy the supplied example and underline its speaker, noun, time cue or evidence words.
- Apply the shown language rule; keep any required ending, accent or paired punctuation.
- Solve the changed independent check, then explain why one offered alternative fails.
- Complete all three new practice cases and use the model to correct the precise word or meaning.
See the method in action
Supplied case: On an original paper grid, start at (0,0) facing north. Read: “Siga recto 1 casilla. Gire a la derecha. Camine 1 casilla.” Gloss: casilla=grid square; casillas=grid squares; siga recto=continue straight; gire=turn; camine=walk. North increases y; east increases x. Which endpoint follows the ordered instructions? Candidate answers: (A) (-1,1) (B) (0,2) (C) (1,1) (D) (5,3). Solution: First move north to (0,1). Turning derecha changes the facing direction to east. Then moving 1 square changes x by 1, giving endpoint (1,1). The instruction order changes which coordinate receives the second move. Final result: (1,1). These original grids supply their coordinate convention and all command glosses. Do not assume right always means east: it does here only because the initial facing direction is north. A turn changes orientation rather than adding an unstated step.

(-2,2)
First move north to (0,2). Turning izquierda changes the facing direction to west. Then moving 2 squares changes x by -2, giving endpoint (-2,2). The instruction order changes which coordinate receives the second move.
Take it further
On an original paper grid, start at (0,0) facing north. Read: “Siga recto 2 casillas. Gire a la izquierda. Camine 4 casillas.” Gloss: casilla=grid square; casillas=grid squares; siga recto=continue straight; gire=turn; camine=walk. North increases y; east increases x. Which endpoint follows the ordered instructions? Candidate answers: (A) (-4,2) (B) (0,6) (C) (2,-4) (D) (4,2). Expected result: (-4,2). First move north to (0,2). Turning izquierda changes the facing direction to west. Then moving 4 squares changes x by -4, giving endpoint (-4,2). The instruction order changes which coordinate receives the second move.
