Teaching ladder LinkedIn Crossclimb #798: students solve 5 clues before touching order. Answers: BARK, DARK, DARE, HARE, HIRE. Only then drag rungs until each neighbor differs by exactly one letter.
Middle phase answers: "Outer layer of a tree" = BARK; "Without any light" = DARK; "“Truth or ___?”" = DARE; "Animal that lost a race to a tortoise in an Aesop fable" = HARE; "Bring on to the workforce" = HIRE.
Ordering phase: the valid middle chain is BARK → DARK → DARE → HARE → HIRE. This permutation is the only valid one-letter chain for these answers.
Rule demo: BACK and BARK differ in exactly one slot — C→R at the third letter (BACK → BARK).
Rule demo: BARK and DARK differ in exactly one slot — B→D at the first letter (BARK → DARK).
Rule demo: DARK and DARE differ in exactly one slot — K→E at the fourth letter (DARK → DARE).
Rule demo: DARE and HARE differ in exactly one slot — D→H at the first letter (DARE → HARE).
Rule demo: HARE and HIRE differ in exactly one slot — A→I at the second letter (HARE → HIRE).
Rule demo: HIRE and FIRE differ in exactly one slot — H→F at the first letter (HIRE → FIRE).
Lesson complete: BACK → BARK → DARK → DARE → HARE → HIRE → FIRE. Remember — middles first, order second, combo last.
