Teaching ladder LinkedIn Crossclimb #898: students solve 5 clues before touching order. Answers: FOLD, FOOD, HOOD, HOOK, ROOK. Only then drag rungs until each neighbor differs by exactly one letter.
Middle phase answers: "Drop out of a poker hand" = FOLD; "What many farms generate" = FOOD; "Robin ___ (legendary outlaw)" = HOOD; "It's at the end of a fishing line" = HOOK; "Game piece that moves up and down and side to side, but not diagonally" = ROOK.
Ordering phase: the valid middle chain is FOLD → FOOD → HOOD → HOOK → ROOK. This permutation is the only valid one-letter chain for these answers.
Rule demo: FOLK and FOLD differ in exactly one slot — K→D at the fourth letter (FOLK → FOLD).
Rule demo: FOLD and FOOD differ in exactly one slot — L→O at the third letter (FOLD → FOOD).
Rule demo: FOOD and HOOD differ in exactly one slot — F→H at the first letter (FOOD → HOOD).
Rule demo: HOOD and HOOK differ in exactly one slot — D→K at the fourth letter (HOOD → HOOK).
Rule demo: HOOK and ROOK differ in exactly one slot — H→R at the first letter (HOOK → ROOK).
Rule demo: ROOK and ROCK differ in exactly one slot — O→C at the third letter (ROOK → ROCK).
Lesson complete: FOLK → FOLD → FOOD → HOOD → HOOK → ROOK → ROCK. Remember — middles first, order second, combo last.
