Teaching LinkedIn Zip #498: students sketch one checkpoint hop at a time on this 6×6 board. 10 checkpoints, 8 walls. Walk the 9 segments before drawing the full line.
Board spotlight: Many blocked edges narrow your options early — map wall bottlenecks before tracing toward the next numbered checkpoint. Wall count 8 on 6×6 shapes which corridors stay open between numbered cells.
Lesson hop 1: show why the path must pass through R2C4 before checkpoint 2. Tight 2-cell hop — checkpoints 1 and 2 sit near each other; still visit every intervening cell exactly once.
Lesson hop 2: show why the path must pass through R5C4 before checkpoint 3. 8 cells link checkpoint 2 at R2C4 to checkpoint 3 at R5C4 with open corridors (no walls on this segment).
Lesson hop 3: show why the path must pass through R5C6 before checkpoint 4. Tight 3-cell hop — checkpoints 3 and 4 sit near each other; still visit every intervening cell exactly once.
Lesson hop 4: show why the path must pass through R5C3 before checkpoint 5. 6 cells link checkpoint 4 at R5C6 to checkpoint 5 at R5C3 with open corridors (no walls on this segment).
Lesson hop 5: show why the path must pass through R5C2 before checkpoint 6. 4 cells link checkpoint 5 at R5C3 to checkpoint 6 at R5C2 with open corridors (no walls on this segment).
Lesson hop 6: show why the path must pass through R5C1 before checkpoint 7. 4 cells link checkpoint 6 at R5C2 to checkpoint 7 at R5C1 with open corridors (no walls on this segment).
Lesson hop 7: show why the path must pass through R2C1 before checkpoint 8. 4 cells link checkpoint 7 at R5C1 to checkpoint 8 at R2C1 with open corridors (no walls on this segment).
Lesson hop 8: show why the path must pass through R2C3 before checkpoint 9. 7 cells link checkpoint 8 at R2C1 to checkpoint 9 at R2C3 with open corridors (no walls on this segment).
Lesson hop 9: show why the path must pass through R2C6 before checkpoint 10. 6 cells link checkpoint 9 at R2C3 to checkpoint 10 at R2C6 with open corridors (no walls on this segment).
Recap: 10 checkpoints, 9 teachable hops, one continuous route. Replay using checkpoint-first planning.
