Teaching ladder LinkedIn Crossclimb #893: students solve 5 clues before touching order. Answers: LOBS, LABS, CABS, CANS, CANE. Only then drag rungs until each neighbor differs by exactly one letter.
Middle phase answers: "High shots, in tennis" = LOBS; "Places for science experiments" = LABS; "Some hired rides, for short" = CABS; "Cylindrical containers" = CANS; "Walking aid" = CANE.
Ordering phase: the valid middle chain is LOBS → LABS → CABS → CANS → CANE. This permutation is the only valid one-letter chain for these answers.
Rule demo: LOIS and LOBS differ in exactly one slot — I→B at the third letter (LOIS → LOBS).
Rule demo: LOBS and LABS differ in exactly one slot — O→A at the second letter (LOBS → LABS).
Rule demo: LABS and CABS differ in exactly one slot — L→C at the first letter (LABS → CABS).
Rule demo: CABS and CANS differ in exactly one slot — B→N at the third letter (CABS → CANS).
Rule demo: CANS and CANE differ in exactly one slot — S→E at the fourth letter (CANS → CANE).
Rule demo: CANE and LANE differ in exactly one slot — C→L at the first letter (CANE → LANE).
Lesson complete: LOIS → LOBS → LABS → CABS → CANS → CANE → LANE. Remember — middles first, order second, combo last.
